Abstract
Using a first-principle approach, we investigate the C 1s core-level shifts of poly(ethylene terephthalate). The geometrical structure of the polymer is first fully relaxed, then the C 1s core-level shifts are obtained using an approach that includes core-hole relaxation. We compute shifts without g eometry relaxation of the excited system, as well as with this relaxation, and find that one of the relative core-level shifts is affected by as much as 0.7 eV by this choice. We compare our ab initio core-level shifts with e xperimental x-ray photoelectron spectroscopy measurements.
