Pulsed ENDOR studies at 95 GHz of the triplet state of 13C60
Fully 13C-enriched C60 has been investigated by pulsed electron-nuclear double-resonance (ENDOR) spectroscopy at W-band frequency at 1.2 K. For molecular C60 the ENDOR spectra reflect the distortion of the molecule upon triplet excitation, and the fine-structure parameter D is found to be negative. For a single crystal of C60 the ENDOR spectra characterize the triplet excitation as delocalized over a pair of neighboring C60 molecules. Copyright 1998 Academic Press.
