Abstract
LixC60 compounds with x between. 6 and 15 are investigated using static and magic-angle spinning C-13 nuclear magnetic resonance spectroscopy. The C-1 3 data show evidence for sp(3) bonding among C-60 molecules. The relative i ntensities of the sp(3) sites suggest a C-60 polymerization and support the prediction of a lattice distortion in the LixC60 low-temperature phase. Th e C-13 chemical shift data indicate an incomplete charge transfer from the Li metal to C-60. DOI: 10.1103/PhysRevB.63.113405.
