The ESR spectrum of Sc[sub 3]C[sub 82] in toluene and CS[sub 2] 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[sub 3]C[sub 82] having the C[sub 3v] symmetry. The line widths of the 22 lines are much broader than that for ScC[sub 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. 8 refs., 4 figs.
