摘要

气相阴离子是探索激发态动力学的理想场所。它们在质量、溶解度、内部温度和构象方面提供了控制。一系列离子源的应用为阴离子系统开辟了广阔的领域,这些系统的动力学在从生物学到恒星形成等领域都非常重要。在此,我们回顾了阴离子光动力学领域的最新实验进展,展示了可以揭示的光动力学和电子捕获过程的详细见解。我们考虑了电子束缚激发态沿整个反应坐标的电子和核超快动力学;电子非束缚态,表明发色团和卡沙法则等光化学概念可转移到电子驱动化学;以及跨越束缚态和非束缚态界面的非价态。最后,我们考虑了阴离子动力学领域的可能发展,这些发展必将保持阴离子动力学的活力和影响力。物理化学年刊》第 75 卷的最终在线出版日期预计为 2024 年 4 月。修订后的预计日期请参见 http://www.annualreviews.org/page/journal/pubdates。

Dynamics of Anions: From Bound to Unbound States and Everything In Between.

Gas-phase anions present an ideal playground for the exploration of excited-state dynamics. They offer control in terms of the mass, extent of solvation, internal temperature, and conformation. The application of a range of ion sources has opened the field to a vast array of anionic systems whose dynamics are important in areas ranging from biology to star formation. Here, we review recent experimental developments in the field of anion photodynamics, demonstrating the detailed insight into photodynamical and electron-capture processes that can be uncovered. We consider the electronic and nuclear ultrafast dynamics of electronically bound excited states along entire reaction coordinates; electronically unbound states showing that photochemical concepts, such as chromophores and Kasha's rule, are transferable to electron-driven chemistry; and nonvalence states that straddle the interface between bound and unbound states. Finally, we consider likely developments that are sure to keep the field of anion dynamics buoyant and impactful.
