We present a comparison between the experimental UPS spectrum of polystyrene and a theoretically simulated spectrum derived from valence effective Hamiltonian (VEH) calculations. The calculations arc carried out on a stereoregular helical isotactic polystyrene chain where the bonds joining the backb
## Recent X-ray diffraction studies provide evidence of: (1) Variation of the C-C bond length in alkali metal graphites and in graphite nitrate. The bond expands when the intercalate is an electron donor and contracts when it is an electron acceptor. (2) Progressive in-plane displacement of carbon
