使用反射式飞行时间质谱仪,研究了Ca+鄄叔丁胺络合物在激光诱导下的反应.得到了反应的光解谱和作为波长函数的光解行为光谱以及各反应通道的分支比.反应有两个通道,Ca+与分子的解离通道和生成产物Ca+NH2 的反应通道,C a+是主要产物,而且在整个激光扫描的范围都存在,并且在530～595 nm 波段是唯一的产物.反应的光解行为光谱显示出明显的无结构的峰,分别对应于络合物的跃迁.结合反应通道的分支比以及量化计算,对这些峰进行了指认,并初步探讨了反应的动力学机理.
The reaction of Ca + -t-butylamine complex under laser-induced reaction was studied by using time of flight mass spectrometry. The photolysis spectra of the reaction and the photolysis behavior spectra as a function of wavelength and the branching ratio of each reaction channel were obtained. There are two Channels, the dissociation channels of Ca + and molecules and the reaction channels of product Ca + NH2, C a + are the main products and exist in the whole range of laser scanning and are the only products in 530-595 nm band. The photolysis behavior spectra showed obvious unstructured peaks corresponding to the transitions of the complexes, respectively. The branching ratio and quantification of the reaction channels were used to identify these peaks and the kinetic mechanism of the reaction was also discussed.
