Webpeaks. Many factors determine the wavenumber shift and intensity at which each functional group’s peak or peaks will be found. Some functional groups are more Raman active than others, and will produce more intense peaks. For example, the C=O bond characteristic of aldehydes is not strongly Raman-active.

The boxes below are labeled by ranges within the infrared spectrum, representing the wavelengths at which specific functional groups absorb energy. The scale is shown in wavenumbers, cm1 Classify each functional group according to the approximate range where it would produce a stretch on the spectrum.
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).

Within a narrow range, each type of bond vibrates at a characteristic wavenumber. This makes infrared spectroscopy useful to identify functional groups in a molecule.
