When I was working with Ewan Blanch on protein Raman Optical Activity spectroscopy, one of the key problems was the lack of a central resource describing the band assignments (the signatures in the spectra that indicate the presence of a particular substructure). I did a bit of simple work towards bringing this together, but never really put it into action.
If you don't know what I'm talking about this probably isn't your cup of tea. It's things like the presence of a peak between X and Y indicates the presence of beta sheet, for example. If this information was all centralised it would be a lot easier to utilise and validate.
With this in mind, I've set up a little form to collate things. If you want to contribute do (but you probably won't). Two important points. 1) I'm only really interested in ROA bands (not Raman), and 2) I want to capture the provenance of the assignment, so at the very least I'd like a Traceable Author Statement.
UPDATE: you can see currently entered assignments (albeit in an unpretty form) here.
Don't bother spamming, it only takes about half a second to get rid of it.
