本文研究了亚稳态原子He(23S)和Ne(3P0.2)与PSCl3分子的反应,获得了PS(B2Ⅱ→X2Ⅱ)和PS(C2→X2Ⅱ)二个谱带的发射光谱.根据碎片的光谱,研究了PS(B2Ⅱ)和PS(C2Ⅱ)的形成速率和振动布居.

关键词: 发光光谱, 反应动力学, 亚稳态, 自由基

The energy transfer reaction of metastable He(23S) and Ne(3P0.2) with PSCl3 was investigated. Emission spectra of PS(B ?X) and PS(C ?X) were observed Based on the spectra of excited fragments the authors estimated the formation rate constants and vibrational population of PS(B) and PS(C). The reaction mechanisms are discussed.

Key words: LUMINESCENT SPECTRA, REACTION KINETICS, METASTABLE STATES, FREE RADICALS
