With this award from the Chemistry Research Instrumentation and Facilities Program, the Department of Chemistry at the University of Missouri in Saint Louis will acquire an upgrade of an existing 300 MHz NMR Spectrometer. This equipment will enhance research in a number of areas, including a) the study of reactions of bimetallic complexes; b) the chemistry of linked metalloborane clusters; c) reactions of small molecules with larger metalloborane clusters; d) dehydrocoupling of hydrosilanes promoted by transition metals; e) synthesis and structural studies of arene oxides & dioxides; f) synthetic applications of (arene)-ruthenium (II) complexes; and g) synthesis and reactions of chiral, non-racemic allylic hydroxy phosphonates.Nuclear Magnetic Resonance (NMR) spectroscopy is the most powerful tool available to chemists for the elucidation of the structure of molecules. It is used to identify unknown substances, to 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. Results from these NMR studies are useful in furthering our understanding of catalysis.

有了化学研究仪器和设施计划颁发的这一奖项，圣路易斯密苏里大学化学系将对现有的300 MHz核磁共振波谱仪进行升级。该设备将加强多个领域的研究，包括a)双金属配合物反应的研究；b)连接的金属簇合物的化学；c)小分子与较大的金属簇合物的反应；d)过渡金属促进的氢硅烷的脱氢偶联；e)芳烃氧化物和二氧化物的合成和结构研究；f)(芳烃)-Ru(II)配合物的合成应用；g)手性、非外消旋烯丙基羟基膦的合成和反应。核磁共振光谱是化学家可以用来阐明分子结构的最强大的工具。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有助于加深我们对催化的理解。
