The authors have investigated the rotational dynamics of C{sub 60} both in solution and the solid state, using {sup 13}C NMR. The rotational correlation times and activation energies of C{sub 60} in several solvents will be reported, and the results compared to measurements in the solid state. These results will then be used to interpret both EPR and NMR experiments on Scandium clusters encapsulated in fullerene cages. Measurement of {sup 45}Sc NMR relaxation rates are found to support conclusions from EPR experiments that the metal clusters form molecules inside the carbon cages.
