FTIR-03 || Overtones, Fermi resonance and combination bands || IR spectroscopy || FTIR spectroscopy

Описание: The IR spectrum is complicated because of the presence of weak overtone, combination, and difference bands. Overtones result from excitation from the ground state to higher energy states, which correspond to integral multiples of the frequency of the fundamental (n). For example, you might observe weak overtone bands at 2v, 3v, . . . . Any kind of physical vibration generates overtones. If you pluck a string on a cello, the string vibrates with a fundamental frequency. However, less-intense vibrations are also set up at several overtone frequencies. An absorption in the infrared at 500 cm−1 may well have an accompanying peak of lower intensity at 1000 cm−1
—an overtone.
