A quantitative investigation reveals that the distribution of intensity within the wings accompanying the vibrational Raman line 656 ${\mathrm{cm}}^{-1\mathrm{}}$ in liquid carbon disulphide is very similar to that obtained in the wings accompanying the Rayleigh lines. The intensity starts from being a maximum at or very near the center, rapidly falls off till a distance of 20 ${\mathrm{cm}}^{-1\mathrm{}}$ is reached after which it gradually diminishes till it fades away altogether. These features are in marked contrast to the predictions of the existing theories of the rotational Raman effect.
