Abstract
Abstract A rapid and simple method for obtaining preliminary information on the identity or structure of an organic molecule is to record an infrared absorption spectrum of the compound. Infrared spectroscopy gives information on molecular structure through the frequencies of vibrations of the molecule. From knowledge of group frequencies, direct information about the presence (or absence) of certain functional groups in an unknown compound is available from an infrared spectrum. Comparison of the spectrum of an unknown material with the spectra of known compounds can lead to the identification of the unknown substance. This section concentrates on spectra–structure correlations in the mid‐ and far‐infrared. An introduction to group frequencies and factors affecting them is given. Tables of group frequencies are provided and a systematic method for the analysis of a spectrum is presented. Examples on the use of spectra–structure correlations are given. A bibliography of the methods and references to collections of spectra are included.
