Abstract

The carbon K-edge absorption spectra of microcyrstalline C₇₀ have been measured using 270-330 eV synchrotron radiation and compared with that of a previously reported microcrystalline C₆₀. The differences in the cage structure between the C₇₀ and C₆₀ fullerenes are clearly reflected in their XANES (X-ray absorption near-edge structures) features. The C₇₀ cluster contains a significant fraction of sp² hybridized carbon bonds as revealed by the presence of a prominent π* resonance in the XANES spectrum.
