Spectroscopy on the Internet
• There are many resources available online:• Presentations, tutorials and guidance• Tables of information• Spectral data for download
• RSC is working hard on Spectroscopy data, platforms and tools to support teaching and provide data
RSC Spectroscopy Resources
• Presently available:• LearnChemistry and the LearnChemistry wiki• ChemSpider
• In Development• RSC Data Repository

Where can SpectralGame Go?• We are interested in supporting extensions
and enhancements to SpectralGame
• More data required….our spectral data repository can host it
• Hosting assigned spectral data and using in SpectralGame makes sense!
• And what about educating/testing students as they do real time assignments?
