摘要：

The ESR spectrum of Sc-3@C-82 in toluene and CS2 solutions exhibits the symmetric hyperfine splitting of the 22 lines with a line width of 0.5 G at room temperature, which is consistent with the structure of Sc-3@C-82 having the C-3v symmetry. The line widths of the 22 lines are much broader than that for Sc@C-82, and show an unusual temperature dependence. The origin of the line widths cannot be explained only by the line broadening effect originating in the hydrodynamic rotation of the whole molecule. We have found that the specific feature of the line widths reflects the intramolecular dynamics which averages between the distinct scandium ion environment.
