| 英文摘要 | we have studied the ion-pair dissociation dynamics of hcl -> cl(-) ((1)s(0)) + h(+) in the 14.41-14.60 ev using tunable xuv laser and the velocity map imaging method. the measured ion-pair yield spectrum has p- and r-branch resolved vibrational structure, which indicates a predissociation mechanism for the ion-pair dissociation. all of-the anisotropy parameters for the angular distribution of the fragments have the limiting values of beta = 2, which suggests that the predissociation occurs via (1)sigma(+) rydber-states. and is fast in comparison with the rotational period of hcl. to understand the predissociation dynamics, the diabatic potential energy curve of the ion-pair state has been calculated at the mrci/cas/vtz level. the experimental and theoretical results obtained in this work have provided a solid foundation for the previously proposed mechanism that the ion-pair dissociation occurs via predissociation of rydberg states converging to hcl(+) (a(2)sigma(+)). |
