Zusammenfassung:
As deduced from electron-energy-loss experiments, the π band in poly(p-phenylene) has a width comparable to that in graphite. The π-band width in poly(p-phenylenesulfide) is considerably narrower, and in poly(p-phenyleneoxide) the π electrons are localized in benzene-derived states. These results are in line with recent theoretical results. In addition, structure in the C1s-π∗ absorption is shown to be due to chemical shifts of C atoms in different coordination.
