【摘要】 用H原子的激光光碎片光谱法研究了HI分子在207nm、121.6nm和364.8nm的光离解动力学过程。通过测量H原子的平动能的分布,可得到激发的I~*(~2P3/2)原子的生成率。在207nm和121.6nm激光的光解下,分别生成25％±6％和73％±6％的激发态I~*原子。其中121.6nm激光的偏振度为79％,激发HI分子的平行跃迁,产生I~+原子。更多还原

【Abstract】 Laser Photofragment spectroscopy of H atoms has been applied to the study of the photodissociation dynamics of HI molecule at 207nm, 121.6nm and 364.8nm. The production of excited Ⅰ^*(²P_8/2 atom is derived by measuring the translational energy distribution of the recoillng H atoms. It is found that 25％±6％ and 73％±6％ of the Ⅰ atoms are formed in their excited states at 207 nm and 121.6 nm, respectively, where the polarization of 121.6nm is 79％ which excited parallel transition of HI molecule to produce Ⅰ^* atoms.更多还原
