Stereodirectional Photodynamics: Experimental and Theoretical Perspectives

Abstract

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 and the excited state Br*, both observable separately by resonance enhanced multiphoton ionization (REMPI). Orientation is evaluated by time of flight measurements combined with slice ion imaging.
