Time-dependent wavepacket propagation techniques have been used to calculate the absorption spectrum and the resonance Raman excitation profiles of the n-'rr \* transition in azobenzene. A comparison of both the calculated absorption spectrum and excitation profiles with experiment has been made. Fr

β¦ Synopsis
Resonance Raman excitation profiles of tram-azobenzene have been measured in the low-energy side of the symmetry-forbidden x*+n absorption maximum at ~450 nm. It is found that this absorption makes a significant contribution to the observed Raman intensities.

Resonance Raman scattering with the Q band of CuTPP shows a peculiar intensity pattern; bands due to combinations and overtones are strorg. whereas the corresponding fundamentals are very weak. By a quantitative analysis of excitation profiles. this phenomenon has been fully accounted for on the bas
