Quantum mechanical analysis of the intensity distribution in spectra of resonant hyper-Raman scattering of polyatomic molecules

Abstract

The quantum-mechanical approach and the method of calculation of the relative intensities of lines of polyatomic molecules, which were previously applied to the analysis of their vibronic absorption and resonant Raman scattering spectra, are assumed to be extended to the description of the intensity distributions in spectra of resonant hyper-Raman scattering of such molecules. This will make it possible to describe all these spectra from the same viewpoint in accordance with their similar physical nature based on a common set of parameters. The basic stages and particular features of the implementation of the method are discussed, and the intensity distribution in the spectrum of resonant hyper-Raman scattering of fluorobenzene is calculated. A comparison of the calculation results with the experimental data indicates that it is expedient to analyze the intensity distributions in the spectra of resonant hyper-Raman scattering of polyatomic molecules using the quantum-mechanical method.
