No resonance enhancement is observed with either T 1g or T 2g electronic transitions in the visible spectral region. Rather it is believed that the Raman transitions obtain intensity by way of virtual excitation of the allowed T 1u electronic transition in the near‐ultraviolet portion of the ...
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...
preresonance Raman spectraliquid crystalline compoundsanomalous intensity enhancement mechanismPre-resonance Raman spectra of certain liquid crystalline compounds, TB4A, TB7A and TB10A, are reported. The anomaly observed in the pre-resonance Raman spectra in the three compounds was initially explained by ...
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.
