The infrared reflection spectra (200-4000cm-l) of the benzophenone single crystal have been recorded at room temperature for three different polarizations. The transverseand longitudinal frequencies of the vibrational modes in the range of 231-1660cm-1 weregiven by using K-K transformation. The static dielectric constants, high frenquency dielectricconstants and refractive indices in near-infrared region were determined by extrapolating thedispersion curves of the dielectric constants and refractive indices given by the K-K transformation. The infrared reflection bands have been assigned. It was shown, that the benzophenone molecules in the crystal are bonded each other by weak van der Waals forces. The appearance of strong reflection bands in the polarized spectra was explained by the aid of crystal structure.
