摘要：

We have measured the V 2p(3/2) and O Is X-ray absorption spectra of single-crystal V2O5 and compared them with linear-combination-of-atomic-orbitals density-of-states (DOS) calculations. The spectra change dramatically with incident angle and the use of polarized light and a single crystal limits the number of transitions possible, revealing spectral features that cannot be resolved using polycrystals (angle integrated). The measured O 1s and V 2p(3/2) spectra agree with the projected unoccupied O 2p and V 3d DOSs respectively, indicating that atomic effects alone cannot adequately describe the absorption spectrum, but that solid-state effects, including V-O hybridization, must be included.
