Abstract
Polarization studies of para-bromchlorobenzene are performed at 77 K. A num ber of new low-frequency, low-intensity Raman lines were observed. Calculat ions of lattice vibrations by the Dean method showed that these lines in th e region of 70 cm(-1) are related to vacancies in the crystal lattice rathe r than to the disorder in the orientation of para-bromchlorobenzene molecul es over para-positions.
