Apparatus for Detecting Transient Absorption[0.3cm］ Spectra in Condensed Phase

Keywords： flash photolysis , transient absorption spectra , condensed phase

本文报道最近研制和建立的凝聚相瞬态吸收光谱及动力学测量的装置,其特点是以低能量,波长可调(4～μm～200～nm)的激光器做为激励光源, 实时地跟踪和检测激光诱导的瞬态产物的吸收谱及其动力学行为。

A novel apparatus for the studies of transient absorption spectroscopy and photo-induced reaction dynamics was developed recently. The unique characters was outlined as follows. A wide frequency- tunable laser system (4～μs～200～nm) with low flux was used as photolysis source. Transient species produced by laser photolysis and/or photochemical reactions can be detected by transient absorption spectra. Dynamic behavior involving radical reaction have been proved by this equipment.
