摘要

六极取向的2-溴丁烷被光解离,并通过234 nm的切片成像技术检测。激光波长对应于C - Br键断裂和Br原子碎片在基态Br (2P3/2)和激发态Br (2P1/2)两个可达的精细结构状态下发射,这两个状态都可以通过共振增强多光子电离(REMPI)分别观察到。通过飞行时间测量结合切片成像来评估定向。

Stereodirectional photodynamics: Experimental and theoretical perspectives
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.
