Conclusions
-
1.
Measurements have been made of the Raman line intensities at 1600 cm−1, and electronic spectra developed for diphenyl and triphenyl derivatives of group V and VIb elements, respectively.
-
2.
Neither the change in intensity of the Raman line, nor the alteration of the spectral characteristics of the long-wave UV band, can be used as measures of the degree of p-π coupling in the above derivatives, the monophenyl derivatives of group V–VI elements, or the phenyl derivatives of group VII elements.
