  • The region between 400 cm-1 and 1500 cm-1 in an IR spectrum is known as the fingerprint region.  It usually contains a large number of peaks, making it difficult to identify individual peaks.  However, the fingerprint region of a given compound is unique and, therefore, can be used to distinguish between compounds.
