在242－260nm波氏范围通过CS2分子的共振增强多光子电离（REMPI）获得了母体离子CS和碎片离子的分质量激发谱．在λ＜246.4nm区间，CS激发谱上呈现出来源于CS2双光子电离的弥散谱带,碎片离子激发谱的归属强烈提示多光子过程中有中性基电子态的CS和S（经由CS2的光解离）产生：（1）CS+的谱带主要来源于中性CS碎片经由单光子跃迁产生的（1＋1）共振增强电离，（2）除了部分S+的谱峰来自CS+的光解外，多数S+的锐谱峰来自中性S原子经由3p3（2D0）4p，3p3（4S0）np（n＝6，7，8）←3p43pJ（J＝2，1,0）双光子跃迁产生的（2＋1）共振增强电离．
The sub-mass excitation spectra of precursor ions CS and fragment ions were obtained by resonance enhanced multiphoton ionization (REMPI) of CS2 molecules in the range of 242-260 nm. In the range of λ <246.4 nm, the CS excitation spectrum shows a diffusion band derived from CS2 two-photon ionization. The attribution of the fragment ion excitation spectrum strongly suggests that the CS and S (via CS2 (1) the band of CS + mainly comes from the (1 + 1) resonance enhanced ionization of neutral CS fragments via single-photon transition, (2) except that some of the peaks of S + come from photolysis of CS + The sharp peaks for S + are from the (2 + 1) 2-photon transition generated by the neutral S atom via the 3p3 (2D0) 4p, 3p3 (4S0) np (n = 6,7,8) ← 3p43pJ (J = Resonance enhanced ionization.
