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.
