Crystalline benzoic acid has been studied by far-infrared spectroscopy in the spectral region of 20–230 cm−1 with a view to a determination and an assignment of the pure lattice and the intermonomer vibrations. An anomalous behaviour, similar to the one found earlier in the mid-IR, is observed for the asymmetric OH…O stretching band with regard to the number of components of the band and its changes as a function of temperature and deuteration. The experiments were carried out for single crystals of fully hydrogenated benzoic acid (−h6) with polarization analysis, and for powder of h6, d1, d5 and d6 benzoic acid at temperatures between 6 and 295 K. An explanation of these anomalies is proposed.
