✦ Synopsis

The resolved multiplet structure of carboxylic ring bands observed for benzoic acid and d,-deuterated benzoic acid by IR and Raman spectroscopy at low temperatures is not in agreement with previous assignments. The temperature dependence of half-widths of some other vibrational bands reveals that more than one mechanism for proton-pair disorder has to be taken into account.

Intermolecular hydrogen bonding plays an important role in the formation of anisotropic interactions in condensed systems. Hydrogen transfer through hydrogen bonds between molecules enables charge and energy transfer to occur in solid chemical and biological systems and has widespread implications f
