The hdtice vtbmtlons of carbon tetrachloride have been studied by Raman and infrared spectroscoptc techniques oter the temperature range 18 K to the melting point at 2.50 K. Comparisons are made aith previous results on CCli and other tetrahedral molecules, and the observed peaks for the monoclinic
Harmonic lattice dynamics calculations have been performed on the low temperature structure of solid CT,,. The theoretically obtained lattice structure agrees with the experimentally determined low temperature structure and the symmetry is found to be P2,/m. The orientationally ordered equilibrium i
