Abstract
The dependence of the relative intensities of Raman lines, having different polarisation characters, on the mode of excitation has been studied using unpolarised, horizontally and vertically polarised incident light. Standard intensities have been obtained in the cases of CCl4, CHCl3, C6H6, C2Cl4, C2H2Cl2, C2H4Cl2, C6H5Cl, C6H5CH3 and C6H5CH2OH with the intensity of the 458 cm−1 line of CCl4 as standard and from these, the values ofα′, the derived polarisability, have been obtained in the case of total symmetric lines characteristic of particular bonds and certain conclusions regarding the intensity variations of corresponding lines in the different liquids have been arrived at. Values of derived anisotropy have also been obtained in the case of the depolarised lines relative to that of 313 cm−1 line in CCl4.
