Molecular vibration - Wikipedia

A molecular vibration occurs when atoms in a molecule are in periodic motion while the molecule as a whole has constant translational and rotational motion. The frequency of the periodic motion is known as a vibration frequency, and the typical frequencies of molecular vibrations range from less than 10 13 to approximately 10 14 Hz, corresponding to wavenumbers of approximately 300 to 3000 cm ...
