Analytical and Surface Chemistry Program funding is provided to this project to support the development of instrumental methods for high pressure studies of the dynamics of gas phase ion reactions. The kinetics and dynamics of reactions between ions and molecules at high pressures are important to a variety of processes occurring in the atmosphere, in combustion processes, and a range of analytical methodologies. The work of this research project will supply much needed information about the dynamics of ion reactions in the relatively unexplored high pressure regime. Both basic gas phase ion chemistry and analytical instrumentation development will be impacted by the work of this project. Ion-molecule reactions occurring at high pressures are the subject of this research project. There are very few methods available which can address questions of reactivity and kinetics in this pressure regime, and the work of this project will develop tools adequate to this task. The basic science understanding obtained from this work will strongly impact atmospheric and combustion chemistry processes.

分析和表面化学计划为该项目提供资金，以支持气相离子反应动力学高压研究的仪器方法的发展。高压下离子和分子之间反应的动力学和动力学对大气中发生的各种过程、燃烧过程和一系列分析方法都很重要。这项研究项目的工作将提供在相对未开发的高压状态下离子反应动力学的急需信息。基础气相离子化学和分析仪器的发展都将受到这个项目工作的影响。在高压下发生的离子-分子反应是本研究项目的主题。很少有可用的方法可以解决这种压力下的反应性和动力学问题，本项目的工作将开发适合这项任务的工具。从这项工作中获得的基础科学理解将强烈影响大气和燃烧化学过程。
