Energy Spectrum and Optical Properties of Fullerene C80(Ih) within the Hubbard Model

Anticommutator Green's functions and energy spectra of fullerene C-80 and endohedral fullerene Y3N@C-80 with symmetry groups I-h have been obtained in an analytical form within the Hubbard model in the mean-field approximation. The group-theory methods are used to classify the energy states and determine the allowed transitions in the energy spectra of C-80 and Y3N@C-80 molecules with symmetry groups I-h.
