Abstract:The polarized Raman scattering and infrared spectra of perchlorate solutions in acetone have been investigated in the CO stretching band region. The cation-dependent separation between the isotropic and anisotropic maxima of Raman band is interpreted in terms of intermolecular coupling of the CO vibrators in the solvation shell of cation. The linear correlation between the isotropic-anisotropic separation and integral intensities of the IR band indicates that the induced dipole mechanism of the coupling dominates.
