N2 - The (Formula presented) NMR line shape of the (Formula presented)(Formula presented) superconductor contains three distinct peaks: one associated with octahedrally coordinated Rb in the fcc lattice of (Formula presented) molecules and two others, labeled (Formula presented) and (Formula presented), 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.
