TUMBLING CERIUM ATOMS INSIDE THE FULLERENE CAGE: iCe_2C_(80)

摘要

We report the spectroscopic work of two Ce-containing incar-fullerenes, iCeC_(82) and iCe_2C_(80). UV/Vis, IR, Raman, TOF-MALDI and ~(13)C NMR were employed to investigate the structural and electronic information of these two major isomers of Ce incar-fullerenes. Tumbling motion of two Ce atoms inside the I_h-C_(80) cage was confirmed and analysed by temperature-dependant ~(13)C NMR.
