摘要: Electron paramagnetic resonance experiments on endohedral Sc3 in C82 show 22 hyperfine coupling split transitions with unusually large linewidths. Both the nuclear and linewidths are found to be strongly temperature dependent. The data that three Sc ions equivalent, suggest they form a trimer which rapidly reorients within cage. A simple model is proposed good agreement data.
