Electronic structure of the polymer phase of CsC60: Refocused INADEQUATE experiments

Carbon-13 MAS refocused INADEQUATE experiments have been carried out on the polymer phase Of CsC60 and provide a complete and unambiguous assignment of the high-resolution carbon-13 MAS spectrum. This allows experimental Knight shifts for each carbon site on the fullerene molecule to be compared with calculated hyperfine coupling constants. The comparison supports a model for the electronic structure which predicts high electron density away from the linkages between fullerene molecules with electron transport dominated by interchain hopping.
