The results of valence-band X-ray photoelectron spectroscopy (XPS) of oxidized carbon fibers are interpreted by X{alpha} calculations on model compounds based upon oxidized coronene fragments. The results indicate that valence-band XPS can distinguish between ether/epoxide and hydroxide surface functionality and that the valence-band region is potentially more sensitive to differences in surface functionality than the core region. XPS data for quinone and hydroquinone with the valence-band region interpreted by X{alpha} calculations are presented and related to the carbon fiber spectra.
