Negative Ion Photoelectron Spectroscopy of Chemically Diverse Cluster Anions

在这项由化学部实验物理化学计划资助的项目中，鲍文将利用负离子光电子能谱来研究溶剂化和反离子、气相双里德堡阴离子、团簇中的过剩电子态(包括偶极束缚的团簇阴离子和团簇类似物)以及生物分子阴离子及其络合物对其他不稳定阴离子的稳定作用。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了影响。这项工作将提供重要的凝聚相现象的分子水平描述，包括那些在生物实体中的现象。这项工作将由研究生和本科生以及博士后研究助理协助进行。在一个积极的外展计划中，还向中学生展示了这项工作，让他们感受到正在进行的前沿科学研究。

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.
