MRI: Acquistion of a Tunable Solid-State Laser System for Applications in Atmospheric Chemistry, Aerosol Analysis, Process Monitoring and Reaction Dynamics

凭借主要研究仪器（MRI）计划的这一奖项，爱荷华州大学化学系将获得一个可调谐固态激光系统，用于大气化学，气溶胶分析，过程监测和反应动力学。这一设备将用于下列用途：a）多相大气化学的激光探测器; B）单粒子质谱法的实时分析; c）燃料电池发动机中一氧化碳的实时分析; d）金属离子分子团的反应动力学和光谱学; e）电荷/质子转移复合物的光化学和光谱学。 激光提供了一束相干单色可见光或红外光，使研究人员能够获得前所未有的细节，有关快速化学反应和/或分子结构的重要信息。 它的使用可能使我们对反应性和非反应性分子性质的理解取得突破。 这些研究将对大气化学和燃烧化学等若干领域产生影响。

With this award from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at the University of Iowa will acquire a tunable solid-state laser system for applications in atmospheric chemistry, aerosol analysis, process monitoring and reaction dynamics. This equipment will be utilized in the following applications: a) laser-based probes of heterogeneous atmospheric chemistry; b) single particle mass spectrometry in real-time; c) real-time analysis of CO in fuel cell engines; d) reaction dynamics and spectroscopy of metal ion-molecule clusters; and e) photochemistry and spectroscopy of charge/proton-transfer complexes. A laser provides a directed beam of coherent monochromatic visible or infrared light, which enables researchers to obtain with unprecedented detail, important information about fast chemical reactions and/or the structure of molecules. Its use may enable breakthroughs in our understanding of the properties of reactive and nonreactive molecules. These studies will have an impact in a number of areas such as atmospheric chemistry and combustion chemistry.
