Structural study of four Ca@C-82 isomers by C-13 NMR spectroscopy
The C-13 NMR spectra of four Ca@C-82 isomers have been measured. The symmetry of isomers I, II, III, and IV are assigned to be C-5, C-3v, C-2, and C-2v, respectively. For isomer IV, the cage is specified to be C-2v(9). (C) 2003 Elsevier B.V. All rights reserved.
