摘要：

The Rb-87 NMR line shape of the Rb3C60 superconductor contains three distinct peaks: one associated with octahedrally coordinated Rb in the fee lattice of C-60 molecules and two others, labeled T and T', both associated with tetrahedrally coordinated Rb. This contrasts with the accepted crystal structure, in which all tetrahedral Rb sites are equivalent. We report multinuclear single and double resonance NMR experiments which probe for effects which could lead to the unexpected splitting, and discuss implications for electronic structure.
