这份来自主要研究仪器（MRI）项目的合同，将使爱荷华大学化学系获得一个可调谐的固态激光系统，用于大气化学、气溶胶分析、过程监测和反应动力学。该设备将用于以下应用：a)基于激光的非均相大气化学探针；B)实时单粒子质谱分析；c)燃料电池发动机CO实时分析；D)金属离子-分子团簇的反应动力学和光谱；e)电荷/质子转移配合物的光化学和光谱学。激光提供定向光束的相干单色可见光或红外光，这使研究人员能够获得前所未有的细节，关于快速化学反应和/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许多领域产生影响。

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.
