X-ray spectroscopic and quantum-chemical characterization of hydrofullerene C60H36

X-ray emission and X-ray photoelectron investigation of hydrofullerene C60H 36 prepared by hydrogen transfer from 9,10-dihydroanthracene to fullerene w as performed. Experimental spectra were interpreted by the results of quant um-chemical calculations of three isomers using PM3 semiempirical method, C ls and C Ka spectra of hydrofullerene C60H36 are in the closest agreement w ith the theoretical spectra of T symmetry isomer in which the benzenoid rin gs occupy tetrahedral positions. Comparison between X-ray emission spectra of C-60, C60H36 and C6H6 shows that benzenoid fragments are really involved in hydrofullerene structure.
