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.

在该项目中，由化学系实验物理化学项目资助，华盛顿大学的Richard A. Loomis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取向的依赖性。 超音速膨胀方法、频率和时间分辨光谱以及飞行时间离子成像光谱测定的组合将用于表征指导双分子相遇结果的分子间势能表面。 初步工作将集中于 He + ICl(B) 和 Ne + ICl(B) 对的非弹性、非反应性解离动力学，为化学反应工作奠定基础。 待研究的双分子反应的初始列表包括用 F2 和 H2 进行电子激发的 ICl(B)。 这项研究将由研究生和感兴趣的本科生进行。卢米斯的教育活动将侧重于让本科生在职业生涯早期亲身接触困难和高级主题，以努力激发更多学生对化学和化学科学的兴趣。量子机械波包项目将纳入本科生量子化学课程。 此外，卢米斯教授还将参加外展项目，旨在 1) 让当地小学、初中和高中的学生接触化学现象并进行学习，2) 通过访问中西部的小型本科学院和大学，让学生有机会了解新颖的研究主题和技术，3) 向兴趣广泛的科学领域和关注点的国际科学作家讲课。
