ResumoThe existence of non-equivalent Sc trimer was confirmed by ESR measurements after the HPLC separation of a Sc-trimer enriched portion from carbon soot. The newly observed ESR signal consists of well-resolved hyperfine structures reproducible by a non-equivalent Se trimer structure. The observed hyperfine structures and line widths were compared with those of [email protected]82 and Sc3@C82, by which the stabilization of the non-equivalent trimer structure is discussed in terms of the hindered molecular motion of the trimer embedded in a fullerene-like carbon network.
