In the multi-photon ionization experiment, the parent ion peak of time-of-flight ( TOF) was observed to become broader with increasing laser power. Briefly, this phenomenon is caused by the space-charge effect of ions. 在分子多光子电离实验中,发现母体离子的飞行时间(TOF)质谱峰随激光强度的提高而展宽,此现象归因于离子团内离子间库仑排斥作用的空间电荷效应。
The experimental results show that the parent ion is extremely unstable. 实验表明,母体离子极不稳定。
The angular distribution of parent molecule ion is highly isotropic while that of the atomic ion is anisotropic. 母体离子的角分布呈现了高度的各向同性,而原子离子则呈现了高度的各向异性分布。
In addition, we have analyzed the multiphoton ionization dissociation ( MPID) mechanism of H 2S from several aspects, and conclude that its MPID process belongs to parent ion fragmentation mechanism. 另外还从多个角度对硫化氢分子的多光子电离解离(MPID)机理进行了分析,推论出其MPID过程应属于母体离子碎裂模式。
It was found that the catalytic properties were changed obviously with the type of parent zeolite, and metal ion. 发现反应活性及活性温度范围取决于分子筛母体与金属离子的种类。
Parent~+ ion was produced by splitting argon with anode gas ionization source. 其中,母系离子[M+H]+由正极气体电离源分裂氩气产生。
