摘　　要：采用色散荧光光谱方法,对308 nm强激光作用下CH3I分子的激发解离过程进行了实验研究.首先对所得色散荧光谱进行了归属,由此确定了主要的荧光产物粒子;依据荧光信号强度随入射激光能量的变化关系,研究了各碎片粒子的产生、激发及荧光跃迁过程,确定了对应的反应通道.所得结果对其他多原子分子的激发解离研究具有参考价值.The process of excition and dissociation of methyl iodide effected by 308 nm strong laser is studied by using disperse fluorescence spectrum method. The main fluorescence production particles are determined by the assignment of these obtained disperse fluorescence spectra. According to the variation of fluorescence signal intensity versus entity laser energy, the processes of the production and exeition of these flagment particles and fluorescence transition are studied, and the corresponding reaction paths are determined. These results may provide reference value for the excition and dissociation study of other polyatomic molecules.
