摘要：

We report on a C-13 NMR investigation of K6C60. The previously reported C-13 NMR measurements of the fully doped alkali fullerides suffered from limited resolution and show very broad spectra which were dominated by chemical shift anisotropy. By applying magic angle spinning (MAS) to K6C60 We obtained a highly resolved C-13 NMR spectrum which shows one isotropic line at 156 ppm at ambient temperature. Careful analysis of this line enabled us to distinguish three separated narrow lines. This result is consistent with orientationally ordered C60 moieties leading to three non-equivalent carbon sites in the saturated compound.
