In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Bowen will use negative ion photoelectron spectroscopy to investigate the stabilization of otherwise unstable anions by solvation and by counter ions, gas-phase double Rydberg anions, excess electron states in clusters including dipole-bound cluster anions and cluster analogs, and bio-molecular anions and their complexes.This project deals with several issues of contemporary physical chemistry, which impact on related fields and on biochemistry. The work will provide molecular level description of important condensed phase phenomena, including those in biological entities. The work will be assisted by graduate and undergraduate students and by postdoctoral research associates. In an active outreach program the work is also presented to middle school students to give them a feel of ongoing forefront scientific research.

在这个由化学部实验物理化学项目资助的项目中，鲍文将使用负离子光电子能谱来研究通过溶剂化和抗衡离子、气相双里德伯阴离子、簇中多余电子态来稳定其他不稳定的阴离子包括偶极结合的簇阴离子和簇类似物，以及生物分子阴离子及其配合物。该项目涉及当代物理化学的几个问题，这些问题对相关领域和生物化学产生影响。 这项工作将为重要的凝聚相现象（包括生物实体中的凝聚相现象）提供分子水平的描述。 这项工作将得到研究生和本科生以及博士后研究员的协助。 在一项积极的推广计划中，该作品还向中学生展示，让他们感受到正在进行的前沿科学研究。
