The low-frequency Raman active lattice vibrations of the 9,10-anthraquinone single crystal were measured at various temperatures from 26°C to −190°C, and the symmetry species of the observed Raman bands were determined by polarization measurements. From a comparison between the observed and calculated frequencies, it seems that Dashevsky’s potential expresses well the intermolecular potential of the 9,10-anthraquinone crystal. It was also found that the temperature dependence of lattice vibrations can be explained reasonably with this potential.
