摘　　要：自由基和激发态原子分子反应装置是一台综合了分子束技术,激光诱导荧光技术,共振多光子电离技术及质谱和化学发光光谱测量技术相结会的功能比较齐全的分子反应动力学研究装置,利用稀有气体(He,Ar,Xe)亚稳态与N_2,CS_2等分子碰撞传能发射光谱测量及C(~3P)+N_2O((?)Σ^+)反应产物CN(X^2Σ^+,V^(?))的激光激发谱测量证实了这台装置具有良好的工作性能。并将装置分为超音束源,质谱室及激光诱导荧光和化学发光谱测量系统四个部分作了详细介绍。The apparatus of studying free radical and excited species reactions has been built in Dalian Institute of Chemical Physics. It consisted of a supersonic molecular beam source with differential pumping system, a quadrupole mass spectrometer with turbine & ion pumping system, and Chemiluminescence, LIF, REMPI spectra detecting system with a computerized data acquisition. The emission spectra of N^+_2(B^2∑^+_u),N_2(B^3∏_g) produced by the collision of N_2(X^1∑^+_g) with He(2~3S), Xe(~3P_(0,2)) respectively and CS(A^1∏) produced by CS_2((?)~1∑^+_(?)) with Ar (~3P_(0.2))have been obtained in our laboratory. The laser excitation spectrum of CN(X^2∑^+) produced by the C(~3P)+N_2O reaction is also presented.
