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.

Erwin D. Poliakoff 博士得到实验物理化学计划的资助，用于研究同步加速器辐射诱导的分子离子荧光。这些测量为了解激发分子中电子运动和核运动如何相关提供了宝贵的见解。而且，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性（弗兰克-康登击穿），以及相关的电子相关效应（连续耦合）。先前的工作已使用色散荧光来证明分辨率不受激发带宽的限制。这种能力将允许进行原本不可行的研究，包括范德瓦尔斯物质的光电离、电离连续体之间形状共振特征的转移以及双电荷双原子离子的荧光的研究。
