I know of several for the gas phase (e.g. HITRAN, GEISA, PNNL) but not the condensed phase. Most seem to be proprietary databases for matching spectra, but don't allow determining absorption as a function of density or path length.
I found your request on quanitative liquid phase infrared absorption spectra, becuase my problem is exactly the same. Did you manage to find one, could you please share it with me?
