Based in the infrared spectrum diagram for benzoic acid, only some of the most prominent peaks for particular bond vibrations are discussed, particularly if benzoic acid has a functional group with a particular characteristic wavenumber peak.

When analyzing an IR spectrum, it is helpful to overlay the diagram below onto the spectrum with our mind to help recognize functional groups. Figure 1. Group frequency and fingerprint regions of the mid-infrared spectrum. The region of the infrared spectrum from 1200 to 700 cm-1 is called the fingerprint region.
23 Νοε 2016 · We can observe and measure this “singing” of bonds by applying IR radiation to a sample and measuring the frequencies at which the radiation is absorbed. The result is a technique known as Infrared Spectroscopy, which is a useful and quick tool for identifying the bonds present in a given molecule.
IR SPECTRUM OF AMIDES. The remainder of this presentation will be focused on the IR identification of various functional groups such as alkenes, alcohols, ketones, carboxylic acids, etc. Basic knowledge of the structures and polarities of these groups is assumed.
