Infrared Spectra of Some Common Functional Groups

WebThe region of the infrared spectrum from 1200 to 700 cm -1 is called the fingerprint region. This region is notable for the large number of infrared bands that are found there. Many different vibrations, including C-O, C-C and C-N single bond stretches, C-H bending vibrations, and some bands due to benzene rings are found in this region. WebThe C–O stretches appear as two or more bands in the region 1300-1000 cm -1.
