Effect of powerful resonant radiation field on degenerate vibrations in polyatomic molecules
Bobovich Ya.S., Bortkevich A.V., Tsenter M.Ya.
We investigate jointly the spectra of resonant spontaneous Raman scattering and resonant simulated Raman scattering of tricyanide and of a number of other polymethine dyes. "Extra" lines were observed in the substance at low frequencies. A hypothesis that these lines belong to components of the field-lifted degeneracy is advanced and justified.
