WebbThe 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.

WebbThe infrared radiations refer to the part of the electromagnetic spectrum between the visible and microwave region. This spectral region is generally subdivided into three portions, near-infrared (14,290 – 4000 cm-1), mid-infrared (4000 – 400 cm-1), and far-infrared (700 – 200 cm-1).
