Ca+-Pyridine络合物的光解反应

使用反射式飞行时间质谱仪,得到 Ca~ -pyridine 络合物在412～ 690nm 的光解谱.从谱图可见,反应有两个通道,一个是 Ca~ 与 pyridine 分子解离开的非反应淬灭过程,这个通道在所有波段都有,且占优势；生成产物 Ca~ NH_2的通道不仅所占比例小,且在530～590nm 波段关闭. 作为激光波长函数的 Action spectrum 显示出明显的峰,对应于络合物的跃迁.反应的分支比也支持了光解谱图的结论.     

Ca+-Pyridine络合物的光解反应

Photodissociation spectra of Ca+-pyridine complex was obtained by reflectron time of flight spectrum (RTOF). Two channels were found from difference photodissociation spectra, one was non-reactive Ca+ cation separation channel, the other one was active channel for product Ca+NH2. Product Ca+ was dominant in the whole region studied and the only product in 530-590 nm region, reactive product Ca+NH2 shared a little present in whole products. Action spectrum as a function of photolysis laser wavelength shows appearance peaks relevant to transitions of complex. Branching ratio supports the information of photodissociation too.
