WebMar 16, 2024 · Infrared radiation is the proper energy to excite vibrations in molecules. The IR spectrum consists of near (4,000-12,800 cm -1 ), mid (200-4,000 cm -1) and far (10-200 cm -1) regions. The mid-IR region is most commonly used for analysis purposes. Vibrational excitations correspond to changes in the internuclear distances within molecules.
