Dissociation dynamics of transient anion formed via electron attachment to sulphur dioxide (SO2)

Abstract

SynopsisWe have investigated the dynamics of dissociative electron attachment to sulfur dioxide (SO2) using velocity slice imaging (VSI) technique. The symmetric dissociation of the transient parent anion results in S− formation whereas its asymmetric dissociation results in the O− and SO− channels. We clearly see the competition between bending and stretch mode of vibrations of the parent anions in S− formation whereas the stretch modes dominate in the other two ions production.
