A priori theoretical considerations lead one to expect that Rb3C60 is a Mott-Hubbard insulator. This has led to the proposal that the superconductor “ Rb3C60” is, in fact, Rb3-εC60 (ε0.06) and, furthermore, that the vacancies are associated with an unexpected, robust splitting in 87Rb NMR. We demonstrate that vacancies, if present, are unrelated to observed NMR splittings.
