In this project, funded by the Experimental Physical Chemistry program of the Chemistry Division, Prof. Richard A. Loomis of Washington University will investigate the dependence of intermolecular interactions and chemical reaction dynamics on the relative orientations of the reactants. A combination of supersonic expansion methods, frequency- and time-resolved spectroscopy, and time-of-flight ion imaging spectrometry will be used to characterize the intermolecular potential energy surfaces that direct the outcome of bimolecular encounters. Initial work will focus on the inelastic, non-reactive dissociation dynamics of the He + ICl(B) and Ne + ICl(B) pairs to establish a foundation for the chemical reaction work. The initial list of bimolecular reactions to be studied includes electronically excited ICl(B) with F2 and H2. This research will be conducted with graduate students and interested undergraduates.Prof. Loomis' educational activities will focus on giving undergraduate students hands-on exposure to difficult and advanced topics early in their careers in an effort to interest more students in chemistry and chemical science. Quantum mechanical wave packet projects will be incorporated into the undergraduate Quantum Chemistry course. In addition, Prof. Loomis will participate in outreach programs aimed at 1) exposing students in local elementary, middle, and high schools to chemical phenomena and learning, 2) through visits to small undergraduate colleges and universities in the Midwest give students an opportunity to learn about novel research topics and techniques, and 3) lecturing to international science writers whose interest span broad areas and concerns in science.

在这个项目中，由化学划分的实验物理化学计划资助，华盛顿大学的理查德·A·鲁米斯教授将研究分子间相互作用和化学反应动力学对反应物相对方向的依赖性。 超音速扩展方法，频率和时间分辨光谱以及飞行时间的离子成像光谱法的结合将用于表征指导双向分子遭遇结果的分子间势能表面。 最初的工作将集中于He + ICL（B）和NE + ICL（B）对的无弹性，非反应性解离动力学，以建立化学反应工作的基础。 要研究的双分子反应的初始列表包括具有F2和H2的电子激发ICL（B）。 这项研究将与研究生和感兴趣的本科生一起进行。 Loomis的教育活动将集中于在职业生涯初期为本科生动手接触困难和高级主题，以使更多的学生对化学和化学科学感兴趣。量子机械波数据包项目将纳入本科量子化学课程。 此外，Loomis教授将参加以1）为目的1）将当地小学，中学和高中的学生展示到化学现象和学习中，2）通过访问中西部的小型本科学院和大学，使学生有机会学习新颖的研究主题和技术，以及3）与他们的兴趣跨越国际科学领域的兴趣跨越广泛的科学领域。
