The following table lists infrared spectroscopy absorptions by frequency regions.
Table 6.1 Characteristic IR Frequencies of Stretching Vibrations. The information in Table 6.1 can be summarized in the diagram for easier identification (Figure 6.3b), in which the IR spectrum is divided into several regions, with the characteristic band of certain groups labeled.
This article will provide a table containing IR spectrum absorbtion frequency values and what they represent.
Infrared Tables (short summary of common absorption frequencies) The values given in the tables that follow are typical values. Specific bands may fall over a range of
