Energy Spectrum and Optical Absorption of Isomer No. 11 of С84 Fullerene of С2 Symmetry Within the Hubbard Model

详细

Energy spectrum of isomer No. 11 of С₈₄ fullerene of С₂ symmetry is calculated within the Hubbard model. Based on the obtained energy spectrum, the optical absorption spectrum is modeled taking into account not only allowed, but also forbidden symmetry transitions. Good qualitative agreement with the experimental data is obtained. This suggests that when studying fullerenes, the intra-site Coulomb interaction of electrons must be taken into account.
