LFμSR studies on the pure fullerenes C60 and C70 show temperature dependent features associated with the reorientational behaviour of the fullerenyl radicals MuC60 and MuC70 in the crystalline host substrate. If not excluded from the experimental setup, molecular oxygen undergoes spin exchange reactions with the radicals. The data for C60 correspond to a situation effectively static at 150 K and fully averaged to isotropy at 300 K, while for C70 the data conspicuously do not conform to the predictions of the pseudostatic model employed in ALC-μSR studies.
