The analysis of the CO stretching vibrational mode of benzaldehyde has been carried out at different concentrations of the solvents (V/V) ranging from 10% to 90% by observing the Raman spectrum. The isotropic band shape and anisotropy shift are discussed qualitatively by taking into account the role of repulsive type of intermolecular forces. The solvent dependent study of the anisotropy shift reveals that the repulsive component of the intermolecular interaction potential may be playing a dominant role in the case of complex molecular systems.
