摘要
The B-2(2), (2)A(2) and B-2(1) ionic excited states of sulfur dioxide were studied by quantum calculations with the density functional theory ( B3LYP functional) and the coupled cluster singles and doubles with perturbative triples [CCSD(T)] methods. The optimized structure of the B-2(2) state was of a transition state correlating to an equilibrium geometry of the C-s point group, contrary to previous studies. The B-2(1) state has two equilibrium structures of a bent and a cyclic geometry. By the computation of Franck-Condon factors, the photoelectron spectrum of the (2)A(2) state was simulated and was found to be in agreement with the experiment, but with different assignments.
