Gas-Phase Ionic Chemistry and Spectroscopy

有机和大分子化学计划通过这一更新奖支持加州帕洛阿尔托斯坦福大学化学系约翰·布劳曼博士的工作。这项工作寻求对气相离子的平衡、动力学、光学和红外光化学的基本理解。实验方法包括离子回旋共振光谱，高压和流动余辉质谱，光学和红外光激发，使用传统光源和激光光源。通过使用各种实验技术研究气相中活性中间体的反应，该工作旨在了解有机化学中一些最基本的问题。将结构与反应性联系起来，比较气相和溶液相的行为，可以深入了解溶剂在影响化学反应结果方面所起的作用。这项工作有望为研究生的教学和研究提供良好的培训。

With this renewal award the Organic and Macromolecular Chemistry Program supports the work of Dr. John I. Brauman of the Department of Chemistry at Stanford University in Palo Alto, California. The work seeks a fundamental understanding of the equilibria, kinetics, and optical and infrared photochemistry of ions in the gas phase. Experimental methods include ion cyclotron resonance spectroscopy, high pressure and flowing afterglow mass spectrometry, and optical and infrared photoexcitation, using both conventional and laser light sources.The work seeks to understand some of the most fundamental issues in organic chemistry, by studying the reactions of reactive intermediates in the gas phase using a variety of experimental techniques. Correlating structure with reactivity and comparing gas phase and solution phase behavior provides insights into the roles solvents play in influencing the outcomes of chemical reactions. The work is expected to provide excellent training for graduate students in both teaching and research.
