The dynamics of chemical reactions are often governed by transient species, including the transition state for activated bimolecular reactions. Such transient species are difficult to study experimentally, but it has proven valuable to prepare and probe transition-state dynamics by the photodetachment of anions with an equilibrium geometry similar to the neutral transition state. In this review, recent experimental advances in photoelectron and photoelectron–photofragment coincidence spectroscopy are discussed, as well as the latest progress in the calculation of multidimensional potential energy surfaces and quantum dynamics calculations that have enabled an extension of studies of transition-state dynamics to increasingly multidimensional polyatomic systems. Examples of important dynamical effects such as mode specificity, tunneling, resonance and product energy disposal in reaction dynamics are discussed.

通过阴离子光解离的瞬态物种动力学

化学反应的动力学通常由瞬态物种控制，包括激活的双分子反应的过渡态。此类瞬态物种很难通过实验进行研究，但事实证明，通过阴离子的光分离具有类似于中性过渡态的平衡态，可以制备和探究过渡态动态，具有重要的价值。在这篇综述中，我们讨论了光电子和光电子-光碎片重合光谱学的最新实验进展，以及多维势能面计算和量子动力学计算的最新进展，这些进展使对过渡态动力学的研究扩展到了越来越多的领域。多维多原子系统。重要的动态效果示例，例如模式特异性，隧穿，
