摘要：

X-ray absorption near-edge structure (XANES) spectra of fullerenes C60, C70 and C76 were measured at the K-edge of carbon. Comparison of XANES and inverse photoemission spectra of C and C70 revealed that the core excitonic effect is small, indicating the usefulness of XANES spectroscopy for probing the density of unoccupied states (DOUS) of fullerenes. The variation of the magnitude of the core excitonic effect among various delocalized pi-electron systems is discussed in relation to the dimensionality and size of the systems. The observed XANES spectra were compared with theoretically calculated DOUS.
