Model calculations are reported on molecules such as ethylene that twist on electronic excitation. Resonance Raman spectra and excitation profiles are calculated for several pairs of torsional potentials. For a 90° twist, the resonance Raman spectra show double-quantum torsional progressions that tend to be very long for resonance in the region of strong absorption. The Raman excitation profiles of the torsional-mode bands resemble the absorption spectrum in that most of the intensity is found… CONTINUE READING
