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
## Abstract Band structure for the T, TG, G and TGTG' conformations of polyethylene are computed in the framework of the extended HΓΌckel method. Significant changes of the Cο£ΏC bands are observed in the density of states and could in principle be detected by an XPS experiment.
Ligand field theory calculations of energy levels were performed for the neutral lanthanide monohalides by treating the molecular electronic states as Ln / free-ion levels perturbed by a ligand field X 0 (where Ln β Ce through Yb and X β F, Cl, Br, or I). The single-atomic-configuration approximatio
