WebMost organic functional groups absorb in the so-called “diagnostic region” of the spectrum at wavenumbers from 1500-4000 cm -1 and can be easily recognized. For example, carbonyl functional groups (C=O) typically show up around 1750 cm -1 and hydroxyl groups (O-H) stretches show up around 3500 cm -1 (see example spectrum below). WebAbsorption of infrared radiation brings about changes in molecular vibrations within molecules and ‘measurements’ of the ways in which bonds vibrate gives rise to infrared spectroscopy. Atom size, bond length and bond strength vary in molecules and so the frequency at which a particular bond absorbs infrared radiation will be ...
