Within the framework of the Hubbard model, the energy spectra of the Cs and C3v isomers of C58 fullerene and dimers based on them are calculated. The obtained curves of the density of electronic states of these systems are compared with the experimental curves of the films, which were obtained by deposition of the Cs and C3v isomers of C58 fullerene on the (1,1,1) gold surface. A comparative analysis of the curves of the density of electronic states shows that in those sites through which a bond is formed between fullerenes, carbon is not in the sp2, but in the sp3 hybridized state. Keywords: fullerene, dimer, energy spectrum, Hubbard model, Hubbard subband, density of electronic states.
