EVALUATION OF CARS SPECTRA - SPECTRA OF SYMMETRICAL MOLECULES IN THE KEILSON-STORER MODEL

The quasiclassical theory of rotational relaxation processes is consid ered for CARS and Raman spectrum of symmetric molecules. The kinetic e quation is solved under arbitrary strength of collisions and the expre ssions describing the smoothed spectral contour are derived. The propo sed processing of experimental data allows one to determine directly t he cross sections of rotational energy relaxation and vibrational deph asing processes. In contrast to existing quantum scaling theories, the bandshape evaluation algorithm does not require time-consuming numeri cal calculations and can be realized on a personal computer.
