Raman spectrum of carbon disulphide
A detailed investigation has been made of the intensity and polarisation characters of the Raman lines in carbon disulphide. It is found that the Q branch of the principal vibration line 656 cm.−1 cannot be separated from the PP and RR branches. The intensity distribution in the latter is similar to that obtained in the wings accompanying the Rayleigh lines in liquids. This line, when excited by λ 4358, exhibits a depolarisation of 0·15 and the value increases to about 0·2 if the exciting wave length is λ 4046. The ratio of intensities of the peaks of 656 and 796 Raman lines has been found to be 9·2 whereas the ratio of the total areas under these lines is obtained as 6·6.
