For example, the most characteristic absorption band in the spectrum of 2-hexanone (Figure 6.3a) is that from the stretching vibration of carbonyl double bond C=O at 1716 cm-1. It is a very strong band comparing to the others on the spectrum. A strong absorbance band in the 1650–1750 cm-1 region indicates that a carbonyl group (C=O) is present.Characteristic IR Absorption Peaks of Functional Groups* Vibration Position (cm-1) Intensity* Notes Alkanes C-H stretch 2990 – 2850 m to s Alkenes ...

The 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.
