Abstract
The X-ray absorption near-edge structure (XANES) spectra of C-76 and f lourinated C-60 (C60Fx) were measured. By comparing XANES and inverse photoemission spectra for various pi-electron systems, the deviation o f XANES from density of unoccupied states (DOUS) by core-excitonic eff ect was shown to decrease with increasing size and dimensionality. The deviation is not so large for fullerenes, and the spectrum of C-76 wa s compared with calculated DOUS. The change of bonding and electronic structure from C-60 to C60Fx is also discussed based on the XANES spec tra.
