The FTIR fingerprint region refers to a specific wavenumber range in an infrared spectrum where complex and unique absorption patterns arise. These patterns are highly characteristic of a molecule and can be used as a “fingerprint” for its identification. The fingerprint region typically encompasses the lower wavenumber region (below 1500 cm-1) and provides valuable information about molecular structure, functional group identification, and chemical bonding. By analyzing the absorption frequencies and intensities in this region, scientists can gain insights into the composition, identity, and molecular characteristics of various compounds.
