摘要

X-ray photoelectron, emission, and Auger electron spectra of diamond, graphite, and fullerene have been analyzed by deMon density-functional theory (DFT) calculations using the model molecules adamantane derivative (C_(10)H_(12)(CH_3)_4), pyrene (C_(16)H_(10)), and C_(60), respectively. The theoretical valence photoelectron, C Kα X-ray emission, and Auger electron spectra spectra for the allotropes are in good accordance with the experimental ones. The combination analysis of the valence X-ray photoelectron and C Kα X emission spectra enables us to divide the valence electronic distribution in the individual contributions for pσ- and pπ-bonding MOs of the carbon allotropes, respectively. The experimental Auger electron spectra of the allotropes and be classified in each range of 1s-2p2p, 1s-2s2p, and 1s-2s2s transitions for C KVV spectra, and in individual contributions of the chemically different carbon atoms from the theoretical analysis.
