The anomaly observed in the pre-resonance Raman spectra in the three compounds was initially explained by the Albrecht-Hutley Model, but its failure leads us to explain the anomalous intensity enhancement mechanism by invoking an interference effect between a weak dipole-forbidden excited state and a...
Pre-resonance Raman intensitiesPre-resonance Raman intensitiesA series expansion for the sum over the vibrational levels of an intermediate electronic state, which occurs in the dispersion theory of the Raman effect, is presented. The convergence properties of the series, as a function of electron鈥...
A study of the Raman, pre‐resonance Raman and electronic spectra of the [VO(C3H2O4)2]2? anion was performed. The excitation profiles of the vibrational modes that show pre‐resonance on excitation with laser lines within the electronic bands in the visible region are reported. On this ...
The preresonance Raman intensity enhancement for the ν C C and ν C N vibrations of TCNE complexed with toluene, benzene and fluorobenzene is established. Conclusions regarding the electronic states responsible for the effect are presented.
Resonance and pre-resonance Raman spectra of solids, aqueous and D2O solutions of adriamycin and daunomycin are reported. The Raman bands are due to the chromophore anthraquinone and are coupled with the first electronic π-π* transition of the molecules. All the observed Raman bands have been...
