The far-infrared ($33-200cm-1$) and Raman ($0-150cm-1$ shifts) spectra of liquid carbon tetrachloride have been studied. Calculations based on the methods of $R.G.Gordon1$ have $shown2$ that in the liquid the $CCl4$ molecule has an effective root-mean-square dipole moment of about 0.2 D and an effective root-mean-square polarizability anisotropy of about $1A3$. 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.
