Abstract

The far-infrared ($33-200 cm^{-1}$) and Raman ($0-150 cm^{-1}$ shifts) spectra of liquid carbon tetrachloride have been studied. Calculations based on the methods of $R. G. Gordon^{1}$ have $shown^{2}$ that in the liquid the $CCl^{4}$ molecule has an effective root-mean-square dipole moment of about 0.2 D and an effective root-mean-square polarizability anisotropy of about $1 A^{3}$. Detailed comparisons of the infrared and Raman correlation functions will be discussed. An effort will be made to quantitatively compare the motion with different models.
