Abstract
Isomerically pure endohedral metallofullerenes Gd@C82(C2v), Ho@C82(C2v), and their monoanions 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 C2v symmetry (no. 9) of fullerene С82 has been calculated. Based on the obtained spectrum, optical absorption spectra of endohedral metallofullerenes Gd@C82 and Ho@C82 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.
