Ca+-叔丁胺络合物的激光诱导反应
摘要:
使用反射式飞行时间质谱仪, 研究了Ca+-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, Ca+-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.

Photo-induced Intra-complex Reactions in Ca+-NH2C(CH3)3
Abstract:
Laser induced reaction of Ca+--tertbutylamine complex was studied by reflection time of flight spectrum (RTOF). Different photodissociation spectra, the action spectrum as function of laser wavelength, and ratio curve of different channels were obtained. Two channels were found, one was Ca+- cation separation channel, the other one was reactive channel for product Ca+-NH2. Product Ca+- was dominant in the whole region studied and the only one in the region 530～595 nm. The action spectrum shows pronounced structureless peaks, which are relevant to the transition of complex. The dynamics of the reaction was discussed at the end.
