Resonant Ionization Dynamics

Erwin D. Poliakoff博士获得了实验物理化学项目的资助，研究同步辐射诱导的分子离子荧光。这些测量结果对电子运动和核运动在激发态分子中如何相互关联提供了有价值的见解；此外，这些结果还将告诉我们银河系中各种光源的起源。这项工作的重点是电子和核运动的相关（frank - condon击穿），以及相关的电子相关效应（连续体耦合）。分散荧光已经在以前的工作中使用，以证明分辨率不受激发带宽的限制。这一能力将使原本无法进行的研究成为可能，包括范德华物质的光电离、电离连续体之间的形状共振特性转移和双电荷双原子离子的荧光。

Dr. Erwin D. Poliakoff is supported by a grant from the Experimental Physical Chemistry Program to study synchrotron radiation induced fluorescence from molecular ions. These measurements give valuable insight into how electronic and nuclear motions are correlated in excited molecules; moreover, these results will also tell us about the origins of various light sources in the galaxy. This work focuses on the correlation of electronic and nuclear motion (Franck-Condon breakdown), as well as related electron correlation effects (continuum coupling). Dispersed fluorescence has been used in previous work to demonstrate that resolution is not limited by the excitation band width. This capability will permit studies that would not otherwise be feasible, including work on the photoionization of van der Waals species, transfer of shape resonant character between ionization continua and fluorescence from doubly-charged diatomic ions.
