## Contribution

It provides combined experimental and theoretical insights into stereodirectional photodynamics of 2-bromobutane, focusing on bond cleavage and fragment state detection.

## Key findings

- Observation of Br and Br* fragments in different fine structure states
- Quantitative analysis of molecular orientation effects
- Insights into the bond dissociation mechanism at 234 nm

## 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.
