Resonant light-scattering spectra of molecules with double-well vibrational potentials by V. A. Morozov; Yu. M. Dubina (624-630).
Examples of excitation spectra lines for resonant Rayleigh and Raman scattering by model molecules with a double-well potential in a vibrational subsystem in both the ground and excited states are calculated based on numerical solutions of a stationary Schrodinger equation for a particle in a double-well potential. The obtained results demonstrate that the given formalism can be used, e.g., to establish the mechanism for transferring the proton of an intramolecular H-bond in the excited molecular electronic state upon monochromatic irradiation using resonant light-scattering spectroscopic data.
