08604 IUPAC Gold Book - fingerprint region 10.1351/goldbook.08604 08604 current 1 Region of a spectrum that contains fingerprint bands as well as bands with characteristic group frequencies. The fingerprint region is often associated with the region of the mid-infrared or Raman spectrum of wavenumbers between \(\pu{1500 cm-1}\) and \(\pu{400 cm-1}\).
