摘要
氢迁移反应是最基本、最重要的化学反应之一,它的发生可诱发碳氢分子产生特殊的碎裂通道,表现出独特的动力学特征。近些年来,随着实验技术以及理论手段的发展,对碳氢分子解离中氢迁移过程背后微观物理机制的理解逐步深化完善。本文以参与碳氢分子解离的氢迁移过程为综述对象,简要介绍了研究氢迁移动力学的实验和理论方法,总结了当前对C_(2)H_(2)、C_(2)H_(4)以及C_(2)H_(6)等碳氢分子解离产生碳碳键对称/非对称断裂通道和H_(3)^(+)离子形成通道的机制的认识,并对后续研究内容作出展望。
As one of the most fundamental and most important chemical reactions,hydrogen migration can trigger unusual fragmentation channels of hydrocarbon molecules,which present unique dynamical characteristics.The development of experimental techniques and theoretical methods in recent years has deepened our understanding on the underlying mechanism for hydrogen migration in the dissociation of hydrocarbon molecules.This review provides an overview on the recent advances in the hydrogen-migration-induced fragmentation dynamics of hydrocarbon molecules.After a brief introduction to the relevant experimental and theoretical methods,we summarize the current understanding of the formation mechanism for C-C bond symmetric/asymmetric breakup and H_(3)^(+)ion channels of hydrocarbon molecules,e.g.C_(2)H_(2),C_(2)H_(4),and C_(2)H_(6).Some further research aspects are finally prospected.
