Abstract:
Taking into account the intrasite Coulomb interaction with the parameter $U\sim$ 10 eV in the approximation of static fluctuations, the energy spectrum of the isomer N 181 $(C_2)$ of the C96 fullerene is calculated, based on which its optical absorption spectrum is modeled. The obtained curve of the optical absorption spectrum at a good qualitative level coincides with the experimental curve. The same curve obtained in the framework of the traditional model without taking into account the intranode Coulomb interaction differs significantly from the experimental curve.
