13C and Alkali NMR Studies of Electronic and Structural Properties of Alkali Fullerides

摘要

Extensive NMR experiments have been performed both on the13C and the alkali NMR in AnC60. In the superconducting A3C60. evidences for uniaxial molecular rotations of the C60and for a low T structural anomaly will be given. The linear chain structure of A1C60is revealed by Magic Angle Spinning NMR, while its magnetic properties are studied by13C and87Rb wideband NMR.
