FDM ATR Dyes Diamond (155 spectra)
FDM ATR Dyes Germanium (146 spectra)
•Part of the FDM ALL ATR Bundle
•Part of the FDM Very Large Bundle
As with several other FDM ATR/FTIR libraries, the collection was completely rerun on a monolithic diamond ATR crystal. Every compound, being dyes, was also run on a germanium ATR crystal. See the FDM ATR Organics for a detailed explanation for recording spectra on both diamond and germanium ATR spectra. Dyes, with functional groups with strong absorbances, also have functional groups with strong refractive index values.
We know of no other ATR/FTIR library of dyes with both diamond and germanium ATR spectra.
See also the FDM FAQ for further discussion of diamond and germanium ATR crystals.
