The room temperature Stokes and anti-Stokes Raman spectra of liquid CCl 4 have been recorded. The intensity ratios of anti-Stokes to Stokes Raman bands as a function of Raman shift are obtained in agreement with polarizability theory. The depolarization ratio ρ (ν) as a function of Raman shift is obtained also in agreement with automatically scanned depolarization ratio ρ (ν). Ratio of the intensity of the isotopic ν 1 bands indicates small deviation from the theoretical relative abundance of CCl 4 isotopes. The intensity ratio of the [ν 3 − ν 4, (ν 1 + ν 4) − ν 4] and ν 1 bands is obtained. The consequences of the presence of different isotopes of CCl 4 on the depolarization ratio of its vibrational bands are discussed. The effects of impurities in liquid CCl 4 on depolarization ratio of the ν 1 band are estimated.
