Abstract :
Slice imaging is used to measure the alignment of Br(2P3/2) and Cl(2P3/2) photofragments from the photodissociation of HBr and HCl, respectively, at 193 nm. In both cases the A1Π1 state is predominantly optically excited, which correlates to mJ=±3/2 for the halogen atom photofragments. However, both the Br and Cl photofragments are measured to populate mostly mJ=±1/2, showing that for both HBr and HCl nonadiabatic transitions transfer more population to the a3Π1 state (which correlates to mJ=±1/2) during dissociation than remains in the A1Π1 state. The interference between these two pathways is also measured.
