In the infrared spectral range the absorption of radiation is associated with the excitation of molecular vibrations. The absorption bands occurring in the IR spectra can be assigned to the vibrations of specific valences of molecules or molecular groups. The identification of these bands is possible with the help of existing extensive databases of IR spectra and model calculations.
