In 2014, this library of ATR/FTIR spectra was expanded from 1010 to 1515 compounds. All spectra were rerun on a monolithic diamond ATR crystal. That means superior spectra and superior search results. 422 compounds were also run on a germanium ATR crystal to provide transmission-like spectra and to address strong refractive index contributions from functional groups with strong absorbances and to improve the baselines.  We know of no other ATR/FTIR library of organic compounds with both diamond and germanium ATR spectra.


Fatty acid methyl esters, saturated & unsaturated; fatty acid ethyl esters; fatty acid butyl esters;  fatty acids up to C18; fats; alcohols from C1 to C22; aldehydes; normal and branched alkanes from C6 to C40; alkenes from C6 to C22; normal, methyl and branched ketones; glycols & glycol ethers; dicarboxcylic acids; 150 flavor & fragrance compounds; alkylbenzenes & chlorobenzenes; phenols & chlorophenols, phthalate esters, amines, amino acids, aromatics from C6 to C16; naphthenes and more.
