MRI: Acquisition of an NMR Spectrometer and Upgrade of an Existing NMR Spectrometer

在重大研究仪器(MRI)计划的支持下，雷诺内华达大学化学系将购买一台400 MHz核磁共振(核磁共振)光谱仪，并对现有的500 MHz多核核磁共振进行升级。该设备将使研究人员能够开展以下研究：a)复杂有机分子的设计和合成；b)金属金属络合物的合成、表征、结合和发光性能；c)有机金属络合物的合成、结构和反应活性，重点是那些适用于水/两相催化的有机金属络合物；d)一维苯类纳米结构的设计合成；e)通过异核核磁共振研究胆红素及其羧酸阴离子在有机和水介质中的立体化学；以及f)过渡金属和主族金属在生物体系中的行为。核磁共振波谱是化学家用来阐明分子结构的最有力的工具之一。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仪是必不可少的。这些核磁共振研究的结果将对合成有机化学、纳米科学和生物化学产生影响。

With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at the University of Nevada in Reno will acquire a 400 MHz nuclear magnetic resonance (NMR) Spectrometer and upgrade an existing 500 MHz multinuclear NMR. This equipment will enable researchers to carry out studies on a) the design and synthesis of complex organic molecules; b) the synthesis, characterization, binding and luminescent properties of metallocryptands; c) the synthesis, structure and reactivity of organometallic complexes with emphasis on those applicable to aqueous/biphasic catalysis; d) the designed synthesis of one-dimensional benzenoid nanostructures; e) the stereochemistry of bilirubin and its carboxylate anions in organic and aqueous media by heteronuclear NMR; and f) the behavior of transition and main group metals in biological systems. Nuclear Magnetic Resonance (NMR) spectroscopy is one of the most powerful tools 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 spectrometers is essential to chemists who are carrying out frontier research. The results from these NMR studies will have an impact in synthetic organic chemistry, nanoscience and biochemistry.
