Your institution may already be a subscriber. infrared reference spectra collection. NIST Standard Reference that these items are necessarily the best available for the purpose. infrared reference spectra collection. Thus IR spectroscopy involves collecting absorption information and analyzing it in the form of a spectrum -- The frequencies at which there are absorptions of IR radiation ("peaks" or "signals") can be correlated directly to bonds within the compound in question. This IR spectrum is from the Coblentz Society's ATR-FT-IR spectrum of Isopropyl alcohol (or isopropanol) (4000 – 225 cm –1) Last updated 14th December, 2015 Institute of Chemistry University of Tartu, Estonia Carboxylic acids show a strong, wide band for the O–H stretch.
