Isomerically pure endohedral metallofullerenes Gd@C.sub.82(C.sub.2v), Ho@C.sub.82(C.sub.2v), and their monoan-ions have been synthesized and separated. The optical absorption spectra of solutions of obtained compounds in o-dichlorobenzene have been studied. Within the Hubbard model, the energy spectrum of isomer of C.sub.2v symmetry (no. 9) of fullerene C.sub.82 has been calculated. Based on the obtained spectrum, optical absorption spectra of endohedral metallofullerenes Gd@C.sub.82 and Ho@C.sub.82 and their monoanions have been simulated. The calculated optical absorption spectra have been compared with experimental ones; it has been found that qualitative agreement between them is observed.
