WebThe region from 1500 - 400 wavenumbers is referred to as the fingerprint region. Absorption bands in this region are generally due to intramolecular phenomena and are highly specific to each material. The specificity of these bands allows computerized data searches within reference libraries to identify a material. WebThe region to the right-hand side of the diagram (from about 1500 to 500 cm -1) usually contains a very complicated series of absorptions. These are mainly due to all manner of bending vibrations within the molecule. This …
