Negative Ion Photoelectron Spectroscopy of Molecular and Cluster Anions

在这项由化学系化学结构、动力学和机理(CSDM-A)计划资助的奖项中，约翰霍普金斯大学的Kit Bowen教授和他的研究生和本科生研究人员正在进行实验，以测量电子与中性分子的结合强度。这些实验的结果对其他化学领域也很重要，包括质谱学、酶学和辐射损伤化学。参与该项目的研究生和本科生将在实验物理化学方面得到极好的培训。鲍文教授还向城市初中生和高中生开放他的实验室，让这些学生接触到最先进的实验室科学。鲍文和他的研究小组正在使用基于激光的光电子能谱对原子和分子进行大量实验。正在开展的项目包括：(1)电子诱导质子转移的研究；(2)分子和团簇中扩散电子态的研究，包括偶极结合阴离子和双里德堡阴离子；(3)核碱基的电子亲和力的测量。在这些测量过程中，鲍文教授和他的学生将进一步开发尖端气相实验化学的新实验工具和方法。

In this award, funded by the Chemical Structure, Dynamics and Mechanisms (CSDM-A) Program of the Division of Chemistry, Professor Kit Bowen of Johns Hopkins University and his graduate and undergraduate student researchers are conducting experiments to measure the strength of electron binding to neutral molecules. The results from these experiments are important to other areas of chemistry, including mass spectrometry, enzymology and the chemistry of radiation damage. Graduate and undergraduate students working on this project will receive excellent training in experimental physical chemistry. Prof. Bowen also opens his laboratory to urban middle and high school students, exposing these students to state-of-the-art laboratory science.Prof. Bowen and his research group are conducting a large number of experiments on atoms and molecules, using laser-based photoelectron spectroscopy. Among the projects being carried out are: (1) the study of electron induced proton transfer; (2) the investigation of diffuse electron states in molecules and clusters including dipole-bound anions and double Rydberg anions; (3) the measurement of the electron affinities of nucleobases. Over the course of these measurements, Prof. Bowen and his students will further develop new experimental tools and methods in cutting-edge gas-phase experimental chemistry.
