CS2 mnltiphoton ionization (MPI) mass spectra induced by a XeCl laser are reported. The dependence of ion intensity on laser intensity and sample pressure is measured. Based on the experimental results and some calculations, the MPI model of CS2 and the forming pathways of ions are described.

本文报道了CS_2在XeCl准分子激光(波长为308nm)诱导下的多光子电离质谱实验.我们测量了各种离子(S~+、CS~+ S_2~+和CS_2~+)强度相对激光强度和样品气量的变化规律,根据这些结果和一些相应的计算确立了CS_2多光子电离的动力学模型和每一种离子的具体生成过程.

The multiphoton ionization (MPI) mass spectra of benzene induced by 308nm laser have been reported, and the dependences of mass spectra intensity on laser power obtained in the paper. The ion fragments in C_5 group are very rich. The integrated ion intensity has maximum value at the power density of about 100MW/cm~2. The possible ionization and fragmentation processes are also discussed.

The multiphoton ionization( MPI) study of diethylamine is reported in this paper. MPI mass spectra were measured in the region of 464~486 nm using a time-of-flight mass spectrometer. Parent ion is created through (2+2) resonance enhanced multiphoton ionization (REMPI ) via 3s Rydberg state. Experimental results demonstrate that " fragment In Ladder" produces the fragment ion distribution.The α-bond and pseudo -α bond cleavages give primary fragment ions, which absorb another photon and dissociate to secondary fragment ions. Rate equation method was used to get a quantitative analysis. The calculative results agree well with experimental results, and rate constants are estimated.

首次研究了二乙胺分子的多光子电离(MPI)过程。实验是在无碰撞的高真空状态下进行的,用飞行时间质谱仪获得了染料激光器在464~486nm波段的二乙胺分子MPI质谱(MS)。母体离子由经(nN,3s)里德堡态的(2+2)共振增强多光子电离(REMPI)产生。各种离子强度随激光波长和强度的变化表明,碎片离子阶梯模型产生了二乙胺分子MPI的碎片离子分布。母体离子经α-键和拟-α键断裂形成初级碎片离子,它们进一步吸收光子并碎裂产生次级碎片离子。利用速率方程进行的定量分析得到了与实验结果相符的结果,并估计了二乙胺分子MPI过程的动力学参数。
