Where are there sources of spectroscopy data (Open or Free to use)? I am looking for additional spectroscopy data to add to ChemSpider so that we can act as a centralized host for spectroscopy data for people to download, reuse and for it to be served up to the SpectralGame (www.spectralgame.com). We already have the NMR data from the Pacific Lutheran University and finished depositing over 300 spectra (NMR,MS,IR,UV-Vis) from Spectraschool.org. Are there other spectral collections we can integrate? Is anyone on this group connected to the RedHen Spectra project that now seems defunct?
