Purchase of a 300 HMz Nuclear Magnetic Resonance Spectrometer

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。化学共享仪器计划的这一奖项将帮助北卡罗来纳大学教堂山分校化学系获得一台300 MHz光谱仪，该光谱仪将用于以下化学领域的研究调查。1.金属有机络合物均相催化剂的结构和机理研究2.金属有机化学中配体精制产物的表征。3.金属膦配位化学。4.光环加成反应的合成应用；螺酮类天然产物的合成。5.超临界流体在离子聚合中作为溶剂的应用。

Nuclear Magnetic Resonance (NMR) Spectroscopy is the most powerful tool available to the chemist 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 areas such as polymers and catalysis, and in biology. This award from the Chemistry Shared Instrumentation Program will help the Department of Chemistry at the University of North Carolina at Chapel Hill acquire a 300 MHz spectrometer which will be used in research investigations in the following areas of chemistry. 1. Structural and Mechanistic Investigations of Organometallic Complexes Which Serve As Homogeneous Catalysts. 2. Characterization of Ligand Elaboration Products in Organometallic Chemistry. 3. Metallophosphine Coordination Chemistry. 4. Synthetic Applications of Photocycloadditions; Synthesis of Spiroketal Natural Products. 5. Utilization of Supercritical Fluids as Solvents in Ionic Polymerizations.
