Abstract
- Dissociative charge exchange reactions between Ar<superscript>+</superscript> ion and trans- /cis- dichloroethylene (trans-/cis-C<subscript>2</subscript>H<subscript>2</subscript>Cl<subscript>2</subscript>) are investigated with the ion-velocity imaging technique. The dechlorinated product C<subscript>2</subscript>H<subscript>2</subscript>Cl<superscript>+</superscript> is the predominant, and most of this product show the spatial distribution around the target, implying that the dissociation occurs in the large impact-parameter collision and via the energy resonant charge transfer. Meanwhile, a few C<subscript>2</subscript>H<subscript>2</subscript>Cl<superscript>+</superscript> locate around the center-of-mass, which is attributed to the fragmentation of intimate association between C<subscript>2</subscript>H<subscript>2</subscript>Cl<subscript>2</subscript> and Ar<superscript>+</superscript> or in the small impact-parameter collision. The product C<subscript>2</subscript>HCl<superscript>+</superscript> exhibits the velocity distribution features similar to those of C<subscript>2</subscript>H<subscript>2</subscript>Cl<superscript>+</superscript>. The rarest product C<subscript>2</subscript>HCl<subscript>2</subscript><superscript>+</superscript> shows the distributions around the molecular target, due to the quick dehydrogenation after the energy-resonant charge transfer in the large impact-parameter collision.
