Abstract
Abstract ESR spectra of M@C82 (M=La, Y) metallofullerene solutions show the monotonic decrease of the metal ion hyperfine coupling constant between −70 and +260°C and changes in the lineshape of Y@C82 signals above 80°C, which were attributed to anharmonic metal-to-cage vibrations and to the motion of Y between different chemisorption sites in a C82 cage, respectively.
