The energy spectrum of fullerene C70 is obtained within the framework of the Hubbard model in the static fluctuation approximation. The energy states are classified and the allowed transitions in the energy spectrum of fullerene C70 are determined using the methods of group theory. Assignments of optical absorption bands experimentally observed for C70 fullerene are suggested based on this spectrum.
