transfer channel for the reaction of HBr+ with HBr is investigated in a state-specific manner by preparing the reagent ion in a selected internal state by resonance-enhanced ionization (REMPI) and monitoring the disappearance of this ion by laser-induced fluorescence (LIF). A rate constant for proton transfer of (6.7 ± 1.6) × 10−10 cm3/s is found. The reaction of HBr+ with HBr and DBr was also studied in
通过共振增强电离(REMPI)以选定的内部状态制备试剂离子并通过激光诱导的荧光监测该离子的消失,以特定于状态的方式研究了HBr +与HBr反应的质子传递通道(LIF)。发现质子转移的速率常数为(6.7±1.6)×10 -10 cm 3 / s。还在选定的离子流管中研究了HBr +与HBr和DBr的反应。发现反应非常复杂,产生电荷转移,质子转移和氢转移产物。通过HBr和DBr中性物去除HBr +的速率常数为(5.3±1.3)×10 -10 cm 3 / s 。
