In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Heaven will conduct research in the field of elementary reaction dynamics to investigate how long-range interaction forces between reactants influence the reaction probability and the partitioning of the energy between the products. High-resolution spectroscopy will be used to map out the long-range potentials for select reaction pairs and associated van der Waals complexes. The project includes a study of the effects of reactant orientation on the unimolecular decay dynamics and the solvation of open-shell species.This project deals with fundamental issues of molecular reaction dynamics, i.e., how molecules react with one another in time and as function of separation. Experiments will be performed on select prototype systems to obtain data that will assist in the development of advanced theoretical models that describe reaction chemistry. The work is done in collaboration with theorists. Students and postdoctoral research associates participate in this research and thereby obtain knowledge and skills that prepare them for employment in industry, government laboratories or academia.

在这个由化学系实验物理化学计划资助的项目中，Heaven将在基元反应动力学领域进行研究，以研究反应物之间的长程相互作用力如何影响反应概率和产物之间的能量分配。 高分辨率光谱将用于绘制出选择的反应对和相关的货车德瓦尔斯复合物的长程电位。 该项目包括研究反应物取向对单分子衰变动力学和开壳层物种溶剂化的影响。该项目涉及分子反应动力学的基本问题，即，分子如何在时间上相互反应以及作为分离的函数。 实验将在选定的原型系统上进行，以获得有助于开发描述反应化学的先进理论模型的数据。 这项工作是与理论家合作完成的。 学生和博士后研究人员参加这项研究，从而获得知识和技能，为他们在工业，政府实验室或学术界就业做好准备。
