超声射流CCl2自由基激光诱导荧光激发谱
摘要:
对CCl4/Ar混合气体脉冲直流高压放电产生CCl2自由基,在超声射流冷却下获得了CCl2 1B1－ 1A1420～600 nm 波长范围的激光诱导荧光激发谱,系统标识了9个带系,81个振动带,其中56个振动带是我们新标识的.通过CCl2自由基的超声射流LIF谱与常温下压力为150 Pa 左右的LIF谱相结合分析,初步证实CCl2自由基电子态带源为17 255.04 cm－1.

Laser Induced Fluorescence Excitation Spectra of CCl2 in a Supersonic Jet-cooled
Abstract:
Laser induced fluorescence excitation spectrum of － 1A1 between 420～600 nm has been measured under the supersonic free-jet conditions.CCl2 was produced by dc discharge of CCl4 seeded in Ar n gas with a ratio of 1/50.81 vibronic bands belonging to the different band systems were assigned,in which 56 vibronic bands were first labeled.Comparing LIF excitation spectra of supersonic jet-cooled CCl2 with LIF excitation spectra of CCl2 at room temperature and under total pressure about 150 Pa, we preliminarily verified the electronic state band origin to be 17 255.04 cm－1.
