    The second negative (A2P u - X

    2P g) system of the O

    +2 ion was produced in a tungsten hollow

    cathode discharge tube using oxygen in neon. This spectrum was recorded with the McMathPierce Fourier transform spectrometer of the National Solar Observatory. A total of ten bandswith v

    = 0 a n d 1 a n d v

    = 6 to 12 in the range 15 94530 218 cm

    - 1were observed and

    rotationally analysed. The line positions of all these bands, along with those of a few addi-tional bands available in the literature, were combined in a global least-squares t. Manymolecular parameters for the various vibrational levels and the equilibrium molecular con-

    stants for the X and A states were estimated. RKR potential energy curves were constructedand FranckCondon factors were calculated for the vibrational bands of the second negative(AX ) system. Some additional information obtained from threshold photoelectron spectro-scopy was used to extend the X 2P g potential curve up to v = 24.

    1. Introduction

    Oxygen, being one of the most abundant constituents

    in the Earths atmosphere, is of great interest to many

    dierent researchers. The oxygen molecule (O2) and itsions have been investigated by spectroscopists for more

    than a century. The band systems of molecular oxygen

    and its ions play a signicant role in the aurora, airglow

    and nightglow [1, 2]. Molecular oxygen may also be an

    important astronomical molecule although it is dicult

    to detect from the surface of the Earth. The microwave

    spectrum (60 GHz) of molecular oxygen [3] is suggestedas a useful probe of the thermal structure of the Earths

    atmosphere. While the SchumannRunge (B3R

    -u - X

    3R

    -g )

    band system in the spectral region 17505350 A is theonly prominent electric dipole transition of molecular

    oxygen, the singly ionized molecular ion O +2 has three

    allowed electric dipole transitions: the rst negative

    ( b4R

    -g - a

    4P u) system (49908530 A ), the second negative

    ( A 2P u - X 2P g ) system (19406530 A ), and the Hopeld( c

    4R

    -u - b

    4R

    -g ) system (19402360 A ). The second nega-

    tive system of O +2 is the subject of this paper.

    Although the rst spectroscopic observation of the

    second negative system of O +2 was mad e in 1914 b y

    Stark [4], the emitter was not correctly identied as

    O+2 until the work of Stevens [5] in 1931. Alm ost 120

    bands of this system were observed at low resolution

    and signicant contributions were made by several

    researchers [612]. The vibrational assignments for

    these bands were originally made by Birge in 1925 and

    soon the v

    number became a topic for further inves

    tions. Mulliken [13] used Birges original numberin

    his review article on the interpretation of band spe

    Mulliken and Stevens [14] increased the v

    values

    posed by Birge by two units. Later on Bhale and

    [12] in 1968 made an upward revision of Mulliken

    Stevens [14] lower state vibrational quantum num

    by one m ore unit. A lbritton et al. [15], Edqvist et al

    and Jonathan et al. [17] calculated the FranckCon

    tively, using the vibrational numbering of the X

    state proposed by B hale and Rao [12] and conr

    that the latest revision of v

    numbering is the co

    one.

    The rotational and ne structure analysis of

    second negative system is not as extensive as the

    resolution work. Stevens [5] and Bozoky [18] were

    rst to perform rotational analyses of some of tbands. Stevens [5], who presented the rst rotati

    analysis of this system, erroneously concluded tha

    upper state is a regular P state. He analysed only

    bands with v

    = 0 and 1. The work of Bozoky [18

    which the bands with v

    = 0, 1, 5, 6, 7 and 8 were r

    tionally analysed, demonstrated that the spin

    coupling constant varies from negative at low v to p

    tive at high v. Bhale [19] analysed the rotational st

    ture of the 08 and 17 bands. On the basis of rst

    in each branch and their intensities Bhale concluded

    the upper state of these two bands is indeed an inverted

    state. Raftery and Richards [20] calculated that the

    spinorbit coupling constant for the A2P u state varies

    from positive at low v to negative at high v. However,

    this proposal was convincingly disproved by subsequent

    researchers. Albritton et al. [21] and also more recently

    Coxon and Haley [22] determined the spinorbit cou-

    pling constants for the vibrational levels of the A state

    using least-squares tting techniques and conrmedBhales [19] conclusions.

    Signicant contributions to the rotational analysis of

    the bands of the second negative system of O+2 came

    from the work of Albritton et al. [21], Bhale and Nar-

    asimham [23], and C olbourn and Douglas [24]. While

    Albritton e t a l. [21] were the rst to perform least-

    squares ts of the data of this band system, Bhale and

    Narasimham [23] re-photographed and analysed some

    of the bands analysed by Stevens [5] and Bozoky [18]

    at a higher dispersion (0. 55 A mm - 1 ) than their prede-cessors. Colbourn and D ouglas [24] extended the rota-

    tional analysis to bands with high v

    values, v

    = 11 to15, and v

    = 0 and 1. For the literature on the second

    negative system of O +2 prior to 1977, the reader is

    referred to the review article by Krupenie [25] and

    Huber and Herzberg [26].

    Spectroscopic work on the second negative system of

    O+2 in the 1980s and the 1990s is limited. Coxon and

    Haley [22] combined their data of this system obtained

    from grating spectra with that of Colbourn and Douglas

    [24] and performed a comprehensive least-squares ana-

    lysis using an eective2P Hamiltonian and the method

    of merging. Schappe e t a l. [27] produced this bandsystem in emission and measured optical-emission

    cross-sections for v

    = 0 to 13. Y eager et a l. [28]

    obtained potential energy curves for various electronic

    states of the O +2 molecule using the multicongurational

    spin tensor electron propagator (MCSTEP) method.They also reported the molecular constants obtained

    using the MCSTEP method. Kong and Hepburn [29],

    in their photoelectron spectroscopic study of O2 using

    coherent XUV, observed high vibrational levels (up to

    v = 24 ) of the X 2P g state of O+2 .

    In the present study we investigated the second nega-

    tive (A 2P u - X 2P g ) system of O+2 , in the spectral region15 94530 218 cm

    - 1, p rod u ced in a tun gsten h ollo w

    cathode source and recorded using a Fourier transform

    spectrometer. Ten bands with v

    = 0 and 1 and v

    = 6 to

    12 were observed and their rotational structure ana-

    lysed. The rotational structure of the 011 and 012

    bands are analysed for the rst time and that of the 0

    10 band is analysed for the rst time since the initial

    analysis of Bozoky [18] in 1937. The wavenumber data

    obtained from our Fourier transform spectra were com-

    bined with selected data of Coxon and Haley [22] in a

    global least-squares t. For the rst time, using the

    of Kong and Hepburn [29], the RK R potential en

    curve for the X2P g state of this molecule is extende

    to the vibrational level v = 24. FranckCondon fac

    for the vibrational bands of the second negative (A

    system were also calculated.

    2. Experimental details

    The second negative (A 2P u - X 2P g) system of theion was produced by accident in a tungsten ho

    cathode discharge. The original goal was to reco

    spectrum of WO. Oxygen at a pressure of 0. 2 Torr

    3.5 Torr of neon were used in a continuous fast ow

    the production of the O+2 ions in a discharge

    221 mA of current. The radiation emitted by O+2directed into the entrance aperture of the McM

    Pierce Fourier transform spectrometer of the Nati

    Solar Observatory at Kitt Peak. Eight scans were

    add ed in 54 min o f integration at a reso lu tion

    . Silicon photodiode detectors were used CuSO4 optical lters to limit the spectral regio

    15 90030 200 cm -1

    . Th e O+2 spectrum recorded in

    source contained many atomic lines of neon and

    enabled us to calibrate the spectrum using the line p

    tions reported by Palmer and Engleman [30]. No

    bration factor was necessary.

    3. Analysis and resultsThe b an ds o f the seco n d n egative (A

    = 6 to 12

    observed in the spectral region of 18 50030 210 cm

    The tungsten hollow cathode discharge used in our w

    provided a very intense spectrum of O +2 . In the ca

    the strong 08 to 012 bands, the rotational en

    levels higher than J = 50 were populated. The b

    region are severely overlapped by

    system. Hence in this spectral region, no rotational

    lysis was performed in spite of having a rich spectru

    O+2 .The computer program PC-DECOMP, develope

    J. W. Brault at the National Solar Observatory,

    used to measure the line positions. The rotational

    proles were tted to Voigt lineshape f unctions.

    strong lines show `ringing caused by the (sin x /x)shape function of the Fourier transform spectrom

    The ringing was eliminated by using the `lter t

    option. The signal-to-noise ratio is about 25 for

    lines of the 10 bands observed in the present work are

    listed in table 1.

    The two electronic states X2P g and A

    2P u involved in

    the second negative system of O+2 belong to Hunds case

    ( a) and Hunds case (b) respectively. For the vibrationallevel of the A

    2P u state, the spinorbit coupling con-

    stants are not only very small ( for v = 0,

    Av = - 3. 5 cm- 1) but change sign for the vibrational

    levels above v = 6. Eight dierent branches, four Pand four R, are identied for each vibrational band.

    The satellite Q branches that are expected in a PPtransition are not observed in our spectra because the

    weak Q branches are completely overlapped by the

    stronger P and R branches. In our earlier work on the

    Swan (3P -

    3P ) system of the C2 molecule [31], the satel-

    lite Q branches were observed in the spectrum produced

    in a supersonic jet source but not in the spectrum pro-

    duced in a hollow cathode source.

    The O+2 ion is a homonuclear diatomic molecule and

    the nuclear spin I of oxygen is zero. Hence the antisym-

    metric (a) energy levels are not populated [32]. Since thes /a symmetry (associated with the permutation of the

    two identical nuclei) alternates with J, every alternatespectral line is missing in the spectrum. For a

    2P -

    2P

    transition this eect is not obvious because of the two-

    fold orbital degeneracy of the P states. In this case one

    of the two K-doublets is missing for each J and, apart

    from the slight `staggering of the lines in a branch, the

    spectrum has a normal appearance. In table 1, the spec-

    tral lines with even ( J - 12) values represent an e etransition and those with odd ( J - 12) values represent

    an f

    f transition.Initially, band-by-band ts of the wavenumber data

    of table 1 were made using the eective N2

    Hamiltonian

    of Brown et al. [33]. The matrix elements for a2P state

    were explicitly listed by A miot et al. [34]. In the present

    work, wavenumber data of the 25, 26, 34, 42, 44,

    45, 53, and 511 bands from Coxon and Haley [22]

    were combined with our Fourier transform data, in the

    nal global least-squares t. Initially, many other bands

    from Coxon and Haley [22] were included in our t.

    However, our least-squares ts indicated problems

    with systematic errors in their data, so that only the

    data from the eight bands mentioned above were used.The data from Colbourn and D ouglas [24], used by

    Coxon and Haley [22], were not used in our global t

    because of their fragmentary nature. Our nal data set

    contained more than 4000 transitions that were tted

    together simultaneously in a nonlinear least-squares t

    and 122 parameters were estimated. The variance of this

    global t was 1.667. Of the 122 parameters estimated in

    this t 82 of them Av, Bv, D v , qv and pv for the levels

    v = 2 to 12, Tv and AD v for v = 3 to 12, Hv for v = 8

    to 11, and pD v for v = 9 to 11 were for the X2P g state

    and the remaining 40, Tv , Av , AD v , Bv , D v , qv and p

    the levels v = 0 to 5 (AD v and qv were not estimate

    the v = 2 level) w ere f or th e A 2P u state. All tparameters along with one standard deviation er

    are listed in table 2 for the X2P g state and in tab

    for the A2P u state. In table 1, the observed minus

    culated values obtained for the line positions using

    constants listed in tables 2 and 3 are also listed.

    obs.- calc. values are not given for a few spectral which were not included in the least-squares t. molecular constants reported in tables 2 and 3 ar

    improvement on the previous work because the majo

    of the measurements were made with a Fourier tr

    form spectrometer.

    Kong and Hepburn [29], in their recent study o

    threshold photoelectron spectrum of O2 using cohe

    XUV radiation, observed several vibrational levels

    to v = 24, except v = 22) of the X 2P g state of theion. The Tv values reported by them for the vibrati

    levels v = 13 to 24 were used in our work. Their tvalues were shifted linearly to bring them to the s

    wavenumber scale as the term values obtained f rom

    constants in table 2. The Bv an d Tv values listed in t

    3 for the A2P u state and those listed in table 2 for

    X2P g state, along with the adjusted term values fo

    v = 13 to 24 levels were tted to the usual polyno

    expressions [32] in powers of (v + 12) to obtain eqbrium molecular constants. From these ts the eq

    brium constants Be , ae , g e , etc., and xe , xexe , xe ye ,

    were estimated for the X2P g a nd A

    2P u states,
