Upgrade of 400 MHz NMR Spectrometer for Faculty-Student Collaborative Research

在主要研究仪器（MRI）计划的支持下，位于欧克莱尔的威斯康星州大学化学系将升级现有的400 MHz核磁共振（NMR）光谱仪。具体而言，该部门将更换控制台并获取带探头的脉冲场梯度放大器和反向检测探头。 该设备将使研究人员能够进行以下研究：a）有机金属烯烃聚合催化剂; B）淀粉样蛋白原纤维形成的监测; c）金属卟啉催化的偶氮染料的氧化降解; d）合成生物无机和有机金属化学; e）荧光染料的合成; f）超分子和液晶科学。 核磁共振（NMR）光谱是化学家用来阐明分子结构的最有力的工具之一。它用于识别未知物质，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。对于从事前沿研究的化学家来说，使用最先进的NMR光谱仪是必不可少的。这些NMR研究的结果将对合成有机化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 Wisconsin in Eau Claire will upgrade an existing 400 MHz nuclear magnetic resonance (NMR) Spectrometer. Specifically, the department will replace the console and acquire a pulsed field gradient amplifier with probe, and an inverse detection probe. This equipment will enable researchers to carry out studies on a) organometallic olefin polymerization catalysts; b) monitoring of amyloid fibril formation; c) oxidative degradation of azo dyes catalyzed by metalloporphorins; d) synthetic bioinorganic and organometallic chemistry; e) synthesis of fluorescent dyes; and f) supramolecular and liquid crystalline science. 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 and biochemistry.
