| 英文摘要 | the ion-pair dissociation dynamics of so2 -> so+ (x-2 pi,nu) + o- (2p(j)) in the excitation energy range 14.87-15.15 ev has been studied using the tunable xuv laser and velocity map imaging method. the o- yield spectrum, the translational energy distributions, and the angular distributions of the photofragments have been measured. the electronic structures and selected cuts of potential energy surfaces for the ion-pair states have been calculated by employing the quantum chemistry calculation method at the casscf/6-311++g** level. the equilibrium structures of the six ion-pair states all have linear geometries. an orbital correlation diagram was drawn to illustrate the ion-pair dissociation mechanism. combining the experimental and theoretical results, it is concluded that the ion-pair dissociation takes place mainly via the predissociation of rydberg states (1)a(1) [((cb1)-b-2)4db(1)] and (1)a(1) [(d(2)a(1))4sa(1)]. the experimental results confirm the previous theoretical calculation results about the symmetry assignments for the energy sequence of so2+ as c(b-2(1)) < d((2)a(1)), |
