Dissociation dynamics of tribromomethane probed by time-resolved coincident ion momentum imaging

ORAL

Abstract

The dissociation dynamics of tribromomethane (CHBr3) induced by single-photon absorption in the UV and deep UV as well as multi-photon absorption in the near-infrared (NIR) are probed by Coulomb explosion imaging employing 28-fs NIR pulses at a peak intensity of 4 x 1014 Wcm-2. Time-dependent effects are observed in several multi-body breakup channels in which up to five ions are measured in coincidence. The time-resolved kinetic energy distributions and ion momentum correlations are analyzed to identify possible pathways leading to isomerization or to HBr and Br2 elimination.
