    • The N=C stretching vibrations should not be regarded as pure oscillators since they are most likely coupled to vibrations localized on the R groups. This will be particularly true for Ph-localized vibrations of the same symmetry with similar frequencies to the N=C stretching vibrations.

    • note
    • It should be noted that Raman bands for nontotally symmetric vibrations can gain intensity if the resonant excited state is vibronically coupled to a second excited state (B-term enhancement, ref 18). Because the extent to which B-term scattering is operative is inversely proportional to the energetic separation between the coupled states, it is usually much less important than A-term scattering. This is particularly true for excited states in which the distortions are large, as expected for the resonant excited states under discussion in this work.
