The X-Ray photoelectron and emission spectra (XPS, XES) of C-, N-, and O-containing polymers [polyvinyl alcohol (PVA), polyethylene oxide (PEO), and dianhydride-4,4’-oxydianiline (PMDA-ODA)] were simulated by deMon density-functional theory (DFT) calculations using the model molecules. The theoretical valence photoelectron and C, N, and O K alpha X-Ray emission spectra showed good agreement with some experimental ones. The combined analysis of the valence XPS and C, N, and O K alpha XES enables us to divide the observed valence electronic distribution into the individual contributions for p sigma-, p pi- and non-bonding MOs of the polymers.
