N2 - Soft X-ray emission and absorption spectra in the Si L region of a number of substituted polysilanes, (SiR2)n, have been obtained using synchrotron radiation to investigate their electronic structures. Studied polysilanes were substituted with methyl (R = CH3), ethyl (C2H5), propyl (n-C3H7), butyl (n-C4H9), pentyl (n-C5H11) and phenyl (C6H5) groups. Although similar spectral features in both X-ray emission and absorption are observed among alkyl-substituted polysilanes, slight differences are distinguished between alkyl- and phenyl-substituted ones. These spectral features are qualitatively reproduced by summing calculated density-of-state spectra for Si3s- and Si3d-orbitals. Thus, spectral features are explained through the hybridization of electronic orbitals in both backbone Si atoms and substituent C atoms.
