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.
