Library Listing – 1,229 spectra

Aldrich FT-IR spectral library related to dyes, indicators, alkynes, nitro and azo compounds.

The Aldrich Material-Specific FT-IR Library collection represents a wide variety of the Aldrich Handbook of Fine Chemicals' most common chemicals divided by similar functional groups. These spectra were assembled from the Aldrich Collection of FT-IR Spectra and the data has been carefully examined and processed by Thermo.

The molecular formula, CAS (Chemical Abstracts Services) registry number, when known, and the location number of the printed spectrum in The Aldrich Library of FT-IR Spectra are available.
