  Abstract

The photodissociation dynamics of bromobenzene near 234 nm has been investigated using a two-dimensional photofragment ion-imaging technique coupled with a state-selective [2+1] resonance-enhanced multiphoton ionization (REMPI) scheme. The nascent Br atoms are produced by the primary C-Br bond dissociation, which leads to the formation of 65 (X% ) and Br(2Pj< sub><="" em=""> , j = 1/2, 3/2). The observed translational energy distributions have been fitted by a single Boltzmann function and two Gaussian functions. Trimodal translational energy distributions of Br(2Pj< sub><="" em=""> ) have been assigned to the direct/indirect dissociation mechanisms originating from the initially excited 3(π,π*) state. The assignments have been confirmed by the recoil anisotropy and distribution width corresponding to the individual components.j<>j<>
