In this award, funded by the Experimental Physical Chemistry Program of the Division of Chemistry, Professor Kit H. Bowen of the Johns Hopkins University, together with his undergraduate, graduate and high school student researchers, will investigate a broad range of chemical topics using gas-phase photoelectron spectroscopy. Some of the systems and topics to be studied include biomolecule anions and clusters, electron-induced proton transfer, diffuse (Rydberg) electron systems, and circular dichroism effects in chiral anions. These are wide-ranging experiments that probe fundamental questions in chemistry. Data from these studies will be of interest to theorists as well as other experimentalists.Studies conducted in the Bowen laboratory are aimed primarily at understanding the ways in which electrons interact with molecules. By studying these interactions in well-controlled gas-phase systems, experimentalists like Bowen provide useful data to understand the chemistry and physics of more complex systems. The acid-base studies that are one of the key components of the present work will shed new light on this simple and ubiquitous form of chemical reaction. In addition to the broad scientific impact of the work in the Bowen laboratory, this project will enable a broad range of young scientists -- from high-school to graduate student researchers -- to pursue cutting-edge physical chemistry research. In addition, Prof. Bowen has a long record of outreach to underrepresented groups and this work will continue.

在这个由化学系实验物理化学项目资助的奖项中，约翰霍普金斯大学的Kit H. Bowen教授将与他的本科生、研究生和高中生研究人员一起，利用气相光电子能谱研究广泛的化学主题。一些系统和主题的研究包括生物分子阴离子和簇，电子诱导的质子转移，扩散（里德堡）电子系统，以及手性阴离子的圆二色性效应。这些实验范围广泛，探讨化学中的基本问题。这些研究的数据将引起理论学家和其他实验学家的兴趣。在Bowen实验室进行的研究主要是为了了解电子与分子相互作用的方式。通过在控制良好的气相系统中研究这些相互作用，像Bowen这样的实验学家为理解更复杂系统的化学和物理提供了有用的数据。酸碱研究是当前工作的关键组成部分之一，它将为这种简单而普遍存在的化学反应形式提供新的线索。除了Bowen实验室工作的广泛科学影响外，该项目还将使广泛的年轻科学家——从高中到研究生研究人员——能够从事前沿的物理化学研究。此外，Bowen教授长期以来一直致力于向代表性不足的群体伸出援手，这项工作将继续下去。
