Title: ‘Extra’ resonances in non‐linear Raman spectroscopy
Abstract: Abstract In the treatment of absorption spectra and Raman excitation profiles of polyatomic molecules, relaxation constants appear as ‘soft’ parameters. It is shown that the spectra of non‐linear Raman scattering under resonance pumping conditions are sensitive to variations in the relaxation constants and the number of active vibrations, especially when ‘extra’ resonances are included. This is demonstrated by calculations of coherent Stokes Raman scattering spectra carried out using the density of states model and displaced independent harmonic oscillators. The use of non‐linear Raman spectra for checking the reliability of the model descriptions of S 0 – S 1 transitions is proposed.
