charge- and atom-transfer reactions between Br + , HBr + , and DBr + ions and HBr and DBr molecules have been studied in a HBr + DBr + He free jet. The ionic reactants in specific internal states were prepared by resonance multiphoton ionization of either HBr or DBr, and the ionic products were analyzed by mass spectrometry. A set of eight energetically possible reactions was considered in each case
在 HBr + DBr + He 自由射流中研究了 Br + 、HBr + 和 DBr + 离子与 HBr 和 DBr 分子之间的电荷和原子转移反应。通过 HBr 或 DBr 的共振多光子电离制备特定内态的离子反应物,并通过质谱分析离子产物。在每种情况下都考虑了一组八种能量可能的反应,包括在近共振电离和光解过程中产生的离子。在适当的反应时间内对动力学方程进行数值积分,并解决优化问题以确定适合实验中测量的所有离子的最终分数的速率系数。还获得了最终分数的解析表达式,并用于更准确地推导速率系数。
