9315857 Poliakoff In this project in the Experimental Physical Chemistry Program of the Chemistry Division, Erwin Poliakoff of Louisiana State University will pursue highly resolved studies of resonant photoionization using synchrotron radiation as the excitation source. The deposition and partitioning of energy in the product ions will be determined from dispersed fluorescence. Highly resolved data are thus accessible over a broad electron energy range to help elucidate the photoejection dynamics. These data will be applied to systems which are vibrationally resolved for polyatomic targets and rotationally resolved for diatomic molecules. %%% In the experiments performed in this project, the motions that electrons make when molecules dissociate under the influence of high energy light will be correlated with the motions of the nuclei. The light used in these studies will come in part from a synchrotron radiation source at Louisiana State University. The data acquired in these studies is inaccessible by other techniques and will be used to guide and shape theoretical models for these processes. ***

在化学学部实验物理化学项目的这个项目中，路易斯安那州立大学的Erwin Poliakoff将使用同步辐射作为激发源进行共振光电离的高分辨率研究。能量在产物离子中的沉积和分配将由分散荧光测定。因此，在广泛的电子能量范围内可以获得高分辨率的数据，以帮助阐明光射动力学。这些数据将应用于多原子目标的振动分辨系统和双原子分子的旋转分辨系统。在本项目进行的实验中，当分子在高能光的影响下离解时，电子所做的运动将与原子核的运动相关联。这些研究中使用的光将部分来自路易斯安那州立大学的同步加速器辐射源。在这些研究中获得的数据是其他技术无法获得的，将用于指导和形成这些过程的理论模型。＊＊＊
