在22和70 ℃下测量了Ca@C-74的C-13 NMR谱。笼对称性被指定为D-3 h。C-13 NMR谱的两个明显特征，每条谱线的不同线宽和在较高温度下的谱线锐化，表明Ca原子在D-3 h笼内的几个稳定位点之间跳跃。(C)2004 Elsevier B. V.保留所有权利。
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.
