Raman spectroscopic studies on acetonitrile and benzonitrile as the liquids and in dilute solutions were used to investigate the vibrational relaxation processes which lead to broadening of the C≡N stretching vibrational band. Line widths of isotropic Raman spectra in a number of solvents revealed the quantitative dependence of vibrational relaxation rate on the hydrodynamic and dispersion forces.
