MRI: Upgrade of Bruker Avance 400 MHz nuclear magnetic resonance spectrometer: Third frequency channel and 60A gradient amplifier and probeheads

在主要研究仪器(MRI)计划的这一奖项下，格林内尔学院化学系将获得400 MHz核磁共振(核磁共振)光谱仪的升级。该设备将使研究人员能够开展以下方面的研究：a)新型有机钨锡络合物的表征、结构和新的反应性研究；b)导电硅氧烷聚合物中的离子传输，这对开发新型锂电池材料至关重要。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无机化学和材料化学产生影响。

With this award from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at Grinnell College will acquire an upgrade of a 400 MHz nuclear magnetic resonance (NMR) Spectrometer. This equipment will enable researchers to carry out studies on a) the characterization, structure and investigation of new reactivity of novel organotungsten-tin complexes; and b) ion transport in conducting siloxane polymers important for the development of novel lithium battery materials. 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 inorganic chemistry and materials chemistry.
