Dissociative charge exchange dynamics of HN2+ and DN2

Dissociative charge exchange dynamics of HN2+ and DN2+

authorCount :4
Translational spectroscopy coupled with coincidence detection techniques has been used to study the dissociation dynamics of ground state H/D+N-2 products resulting from charge exchange between keV beams of HN2+/DN2+ and cesium. Analysis of the product kinetic energy release suggests that dissociation of HN2 and DN2 proceeds from initial populations in the (2)A '', 2 (2)A ', and 3s Rydberg electronic states of the neutral molecule. Although all three excited electronic states must eventually couple to the 1 (2)A ' ground state of HN2/DN2, the resulting dissociation dynamics exhibit a significant dependence on the initial electronic state. Potential mechanisms are discussed in light of the observed product kinetic energy release distributions.
