The anisotropic components of the Raman band corresponding to the CO stretching mode of the p ‐methylacetophenone, benzaldehyde, cyclohexanone, N , N ‐dimethylacetamide and N , N ‐dimethylformamide were studied in acetonitrile and benzene solvents. For the first time it has been shown that the van der Waals volume plays a significant role in the line broadening mechanism. The interpretation of the data has been attempted keeping in view van der Waals volume and multipole–multipole interactions. Copyright © 1999 John Wiley & Sons, Ltd.
