摘要：

Upon excitation of a single crystal of C60 in the visible, microwave transitions have been detected optically in zero field. The transitions derive from triplet states and their frequencies verify that these states are delocalized over more than one C60 molecule, as previously inferred from EPR experiments. Different triplet states seem to correspond to excitations that are trapped in different domains of the crystal which indicates that structural or impurity-induced defects may be involved.
