摘要：

Optical absorption spectra of higher fullerenes (C70 and C76) as well as of C60 are calculated by a tight binding model with a long-range Coulomb interaction. A reasonable parameter set gives calculated spectra which are in overall agreement with those obtained from experiments Of C60 and C70 in solutions. The variations of the spectral shape are discussed in relation to the symmetry reduction from C60 and C70 to C76: the optical gap decreases and the spectra exhibit a larger number of small structures in the dependences on the excitation energy.
