## Abstract Raman and infrared spectroscopic studies of benzoic acid dimers and crystals have been made. Molecular and crystal normal modes have been calculated. An assignment of the observed spectra has been proposed and some specific modes discussed.
Benzoic acid molecules form a dimeric unit of carboxyl groups in the crystalline phase and two acid protons form a pair. In the case of a proton/deuteron mixed hydrogen-bond system, proton-deuteron pairs (HD pairs) as dimers may exist in a stochastic distribution probability depending on the mole fr
