| Abstract: | A density-matrix theory of resonance scattering spectroscopy is presented to characterize the relaxation processes which may be studied in these spectra. The distinction between Resonance Raman and Fluorescence emerges clearly from this treatment. It is shown that novel properties of the rotational and vibrational relaxation may be obtained from the lineshape of the scattered light. A new effect is discovered in the Resonance Raman excitation profile which, in principle, could be used to study the relaxation rate between specific vibronic levels of an excited electronic state. |
