molecular vibration

[mə′lek·yə·lər vī′brā·shən]
(physical chemistry)
The theory that all atoms within a molecule are in continuous motion, vibrating at definite frequencies specific to the molecular structure as a whole as well as to groups of atoms within the molecule; the basis of spectroscopic analysis.

Vibrational spectroscopic interests include studies of the overtone - combination spectra of crystalline hydrates at low temperatures and analyzing the data to give local mode coupling constants between OH oscillators, harmonic frequencies and anharmonicity constants (Walker) and the application of resonance Raman spectroscopy to provide information about the vibrational coupling to electronic transitions (Lever).
