الوصف: Experimental studies of the dynamics near the molecular dissociation threshold are frequently frustrated, due to the small cross sections and the demand for identification of close-lying electronic states or nuclear motions with multiple degrees of freedom. Using the high-resolution anion velocity map imaging technique, here we report a dynamics study of the dissociations of anionic nitrogen dioxide in low-lying resonant states formed by electron attachment [e – + NO 2 (X 2 A 1 ) → NO 2 – → NO (X 2 Π) + O – ( 2 P)]. The long-term puzzling issues about the near-threshold dissociations of NO 2 – are settled. We suggest that three low-lying resonant states ( 1 B 1 , 3 B 1 , and 3 B 2 ) of NO 2 – contribute to the production of O – at attachment energies of <5 eV. Furthermore, B 1 and B 2 symmetries of the resonant states lead to different anisotropies of the O – angular distribution. At the relatively high electron attachment energies, a prompt fragmentation in the molecular bent conformation competes with an indirect dissociation in the straightened conformation.
