Hexapole oriented 2-bromobutane is photodissociated and detected by a slice-ion-imaging technique at 234 nm. The laser wavelength corresponds to the C - Br bond breaking with emission of a Br atom fragment in two accessible fine-structure states: the ground state Br (2P3/2) and the excited state Br (2P1/2), both observable separately by resonance-enhanced multiphoton ionization (REMPI). Orientation is evaluated by time-of-flight measurements combined with slice-ion-imaging. © 2016 Author(s).
