The C-13 NMR spectra of Ca@C-74 have been measured at 22 and 70 degreesC. The cage symmetry is assigned to be D-3h. Two distinct features of the C-13 NMR spectra, different linewidths of each line and line sharpening at higher temperature, indicate that the Ca atom hops between the several stable sites inside the D-3h cage.
