	abstract = {The X-ray photoelectron spectra of eight polymers [(CH2CH2)(n), (CH2CH2NH)(n), (CH2O)(n), (CH2CH2S)(n), (CH(2)CHX)(n), and (CH(2)CX(2))(n) (X = F, Cl)] were analyzed by the deMon density-functional method using the model oligomers. Calculated AIK a valence photoelectron spectra were obtained using Gaussian line shape functions of an approximate Line width (0.10I(k)), where I-k = I-k{\textquoteright} - WD, I-k{\textquoteright} is the vertical ionization potential of each MO, and WD is a shift to account for sample work function, polarization energy, and other effects. The theoretical spectra showed good agreement with the experimental spectra of the polymers between 0 and 40 eV. The core-electron binding energies (CEBEs) of C1s, N1s, O1s, F1s, S2p, and Cl2p of the model oligomers were calculated by unrestricted generalized transition-state models. The difference between the calculated and the experimental CEBEs reflects the trend in WDs of the polymers.},

	abstract = {The HAM/3 method was used to provide a better assignment of the valence X-ray photoelectron spectra of 16 polymers involving nitrogen, oxygen, fluorine, a glucose unit, and a benzene nucleus using the monomer, dimer or trimer model molecules without consideration of the contraction factor of the energy scale. The calculated A1 K alpha photoelectron spectra were obtained using Gaussian functions of a fixed approximate linewidth, 0.10 I-k and I-k=I-k{\textquoteright}-WD, where I-K{\textquoteright} is the vertical ionization potential of each MO and WD is an approximate shift to account for the work function of the sample and other energy (polarization energy and so on) effects. We assumed that WD corresponds to the shift that we must apply before we can compare the calculated spectrum for the single model molecule with the observed spectrum for the solid. The approximate linewidth corresponds to the experimental result that the inner valence spectra are broader. The theoretical spectra showed good agreement with the spectra of the polymers observed between 0-40 eV.},
