Isotropic Raman line broadening studies were carried out for the CO stretching mode of vibration in N , N ‐dimethylformamide and cyclohexanone molecules in solution. The broadening for the Raman band is explained on the basis of hydrodynamic, multipole‐multipole, induction and dispersion forces. The intercept on the linear graph [Γ iso vs f (ρ, η, n )] is explained on the basis of induction forces and multipole interactions for dipolar and non‐dipolar solvents.
