摘要：
State-specific multireference Moller-Plesset perturbation theory has been applied to the study of valence and Rydberg excitation energies of benzene. The results compare well with experiment. The calculated valence pi - pi* excitation energies (experimental values in parentheses) are B-1(2u), 4.77 (4.90), B-1(1u), 6.28 (6.20), (1)E(1u), 6.98 (6.94) and (1)E(2g), 7.88 (7.80) eV. Results of similar accuracy are obtained for the valence triplet excited states. The Rydberg excitation energies are also predicted with an accuracy of 0.18 eV or better.
