Kit H. Bowen, Jr. of Johns Hopkins University is supported by an award from the Chemical Structure, Dynamics, and Mechanism Program of the Chemistry Division to investigate, with his graduate, undergraduate, and high school researchers, a broad range of chemical topics using gas-phase, anion photoelectron spectroscopy. Systems under study include negative ions of bio-molecules, diffuse excess electron states, and species formed by electron-induced proton transfer. All of these are related to fundamental questions and issues in chemistry and related fields. The synergy between these experiments and the work of Bowen's theoretical colleagues leads to yet deeper insight into structural, dynamical, and mechanistic aspects of these problems. This research expands the frontiers of knowledge in fields as diverse as mass spectrometry, oncology, electrochemistry, analytical chemistry, enzymology, and radiation chemistry/biology. It shows us how electrons interact with molecules and collections of molecules (clusters) and how the resultant anions interact with other molecules. This work contributes strongly to the education of graduate students and undergraduates. It also provides high school students with a glimpse into scientific research.

约翰·霍普金斯大学的 Kit H. Bowen, Jr. 获得化学系化学结构、动力学和机制项目的资助，与他的研究生、本科生和高中研究人员一起研究广泛的化学主题使用气相阴离子光电子能谱。正在研究的系统包括生物分子的负离子、扩散的过量电子态以及由电子诱导的质子转移形成的物质。所有这些都与化学及相关领域的基本问题有关。这些实验与鲍文的理论同事的工作之间的协同作用使人们对这些问题的结构、动力学和机械方面有了更深入的了解。这项研究扩展了质谱、肿瘤学、电化学、分析化学、酶学和辐射化学/生物学等多个领域的知识前沿。它向我们展示了电子如何与分子和分子集合（团簇）相互作用，以及由此产生的阴离子如何与其他分子相互作用。这项工作对研究生和本科生的教育做出了巨大贡献。它还为高中生提供了了解科学研究的机会。
