Observations
•General shape the same
•Intensities different-most dilute solution has overall lower intensity as expected-50% dilution shows increase in intensity at most optical frequencies but NOT at the frequency with the highest peak (???) […Saturation?]
•Smoothness different-smoothness of curve decreases as we move from highest to lowest concentration (possibly lower concentrations = increased sensitivity… or not?)
