Dunning is supported by the Experimental Physical Chemistry Program to continue his studies of chemical processes induced by high Rydberg atoms. A comprehensive study of the formation and properties of a variety of negative ion species will be performed, with emphasis on (1) the dynamics of dissociative electron capture at thermal and sub-thermal electron energies, (2) the lifetimes of autodetaching species and their stabilization by energy transfer via interactions with a second body, (3) the physical and chemical properties of dipole-bound negative ions, and (4) the search for quadrupole-bound negative ions. Outcomes from this research are expected to enhance the fundamental understanding of electron exchange between donor and acceptor systems.A large number of chemical reactions involve the transfer of electrons between molecules. Rydberg atom collision methods provide new opportunities for improving the understanding of electron exchange processes leading to negative ions. Negative ions and their properties impact various practical applications, including plasma processing of materials and the development of nonconducting media for high-voltage electrical equipment.

邓宁是由实验物理化学计划的支持，继续他的高里德堡原子诱导的化学过程的研究。 将对各种负离子物种的形成和性质进行全面研究，重点是（1）在热和亚热电子能量下解离电子捕获的动力学，（2）自动分离物种的寿命及其通过与第二体相互作用的能量转移的稳定性，（3）偶极束缚负离子的物理和化学性质，（4）寻找四极束缚负离子。 该研究的结果有望加深对供体和受体系统之间电子交换的基本理解。大量的化学反应涉及分子之间的电子转移。 里德伯原子碰撞方法提供了新的机会，提高电子交换过程的理解，导致负离子。 负离子及其特性影响着各种实际应用，包括材料的等离子体处理和高压电气设备的非导电介质的开发。
