Abstract: The electronic absorption spectra of permethylated polysilanes, Me (SiMe&Me, are discussed, together with the possibility that the perturbation of the spectra by various substituents may provide an estimate of (p-+ d), bonding, The various possible assignments of the ground and excited states of the long-wavelength absorption band are considered in the light of ionization potential measurements, and the spectral properties of phenyl ...
