This award from the Chemistry Research Instrumentation and Facilities Program will assist the Department of Chemistry at the University of Minnesota in the purchase of a high resolution mass spectrometer, x-ray diffractometer, and a high field NMR spectrometer. The faculty members whose research is dependent upon mass spectroscopy will greatly benefit from the acquisition of these instruments. Research projects to be carried out with these instruments include: (1) Probing Nucleation Phenomena in Chemical Vapor Depositions; (2) Gas Phase Ion-Molecule Reactions; (3) An Investigation of Multielectron Transfer Reactions in Organometallic Complexes; (4) Synthesis and Characterization of Transition Metal-Gold Cluster Compounds; (5) Synthetic Modeling of Copper-Nitrogen Oxide Interactions in Proteins and Heterogeneous Catalysts and Development of C3-Symmetric and Optically Active Polypyrazole; (6) Surface Chemistry of Chromatography Stationary Phases; (7) Stacking Faults and Polytypism in Nanocrystalline Materials; (8) Detection of Volatile Organic Compounds (VOC) by Linear Chain Pt Compounds; (9) NMR Studies of Metal Oxide Catalysts; and (10) Catalysis with Supported Transition Metal-Gold Cluster Compounds. A high resolution mass spectrometer is an instrument used to measure the precise molecular weight of a molecular ion. This information is an important piece of data used to help determine the atomic composition and, sometimes, the molecular geometry of a molecule. It is one of the essential tools needed to learn the detailed structure of newly synthesized molecules. The x-ray diffractometer is used to make accurate and precise measurements of the full three- dimensional structure of a molecule. The information obtained gives the precise values of all the bond distances and bond angles of a given molecule and it gives accurate information about the spatial arrangement of that molecule relative to the neighboring molecules. Nuclear Magnetic Resonance (NM R) spectroscopy is the most powerful tool available to chemists for the elucidation of the structure of molecules. It is used to identify unknown substances, characterize specific arrangements of atoms within molecules, and to study the dynamics of interactions between molecules in solution. Access to state-of-the-art NMR spectrometry is essential to chemists who are carrying out frontier research. The results from these NMR studies are useful in the areas such as polymers and catalysis, and in biology.

化学研究仪器和设施计划的这一奖项将帮助明尼苏达大学化学系购买高分辨率质谱仪、X射线衍射仪和高场核磁共振光谱仪。那些研究依赖于质谱学的教职员工将从这些仪器的获得中受益匪浅。将利用这些仪器开展的研究项目包括：(1)探测化学气相沉积中的成核现象；(2)气相离子-分子反应；(3)有机金属络合物中多电子转移反应的研究；(4)过渡金属-金簇合物的合成和表征；(5)蛋白质和多相催化剂中铜-氮氧化物相互作用的合成模拟和C3对称光学活性聚吡拉唑的开发；(6)色谱固定相的表面化学；(7)纳米晶体材料中的堆积缺陷和多型性；(8)直链铂化合物对挥发性有机化合物(VOC)的检测；(9)金属氧化物催化剂的核磁共振研究；(10)负载型过渡金属-金簇合物的催化。高分辨率质谱仪是一种用来测量分子离子精确分子量的仪器。这些信息是一条重要的数据，用来帮助确定分子的原子组成，有时还有助于确定分子的几何形状。它是了解新合成分子的详细结构所需的基本工具之一。X射线衍射仪是用来精确和精确地测量分子的全部三维结构。得到的信息给出了给定分子的所有键距和键角的精确值，并提供了关于该分子相对于邻近分子的空间排列的准确信息。核磁共振波谱是化学家用来解释分子结构的最有力的工具。它被用来识别未知物质，表征分子内原子的特定排列，并研究溶液中分子之间相互作用的动力学。对于正在进行前沿研究的化学家来说，获得最先进的核磁共振光谱是必不可少的。这些核磁共振研究的结果在聚合物和催化等领域以及生物学中都是有用的。
