I'm sure everyone here has, at some point, wondered what the UV/vis spectrum of a particular metal salt looks like in a given solvent. Often, the availble information is limited to a couple of peak wavelengths and molar absorptivities, if you're lucky. In my classes, I often keep using the same spectra found in Miessler, Tarr, and Fischer, which, themsevles, come from a 1962 book, "Absorption Spectra and Chemical Bonding in Complexes" by Jorgensen. It's frustrating that there doesn't seem to be an extensive database of electronic spectra (NIST Chemistry Webbook doesn't have much in the way of transition metal salts).
So, I have two questions:
1. Does anyone know about a database that I might be overlooking? Maybe IUPAC has something?
2. If what I'm describing doesn't exist, is there interest in working towards creating it? It would be a large project, and it would lend itself to distribution across many sites.
