Abstract

Using time-of-flight mass spectroscopy and resonance-enhanced multiphoton ionization (REMPI) scheme, the photodissociation of two alkyl bromides (C₂H₅Br, n-C₃H₇Br) and bromobenzene (C₆H₅Br) near 234 and 267 nm was investigated. The branching ratios N(Br^*)/N(Br) of the compounds at two wavelengths were measured, and the relationships between the branching ratio and the photolysis wavelengths and among the potential energy surfaces of the low excited states were explained based on our ab initio calculations.

Key words: resonance-enhanced multiphoton ionization, photodissociation, branching ratio, bromide
