Fingerprint region

Definition

In infrared spectroscopy, the fingerprint region refers to the area of an infrared spectrum, typically below 1500 cm^-1, characterized by a complex pattern of peaks unique to each compound. This region is used to identify specific compounds by comparing their spectra with known references.
