Acquisition of a 500 MHz NMR Spectrometer

凭借这项来自主要研究仪器计划（MRI）的奖项，Krishna Kumar和同事大卫L。大卫·卡普兰Lee，Elena V. Rybak-Akimova和大卫R.来自塔夫茨大学的Walt将获得一台具有脉冲场梯度的双通道500 MHz NMR光谱仪，供该大学梅德福校区三个系和两所学校的多名研究人员使用。 NMR光谱仪将使化学和生物科学领域的各种研究人员能够进行研究，从有机金属/蛋白质复合物和纤维素聚合物的表征，用于分析非天然氟化肽和指导超分子自组装的蛋白质的翻译后修饰。核磁共振（NMR）光谱学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/无机化学和生物化学产生影响。

With this award from the Major Research Instrumentation program (MRI), Krishna Kumar and colleagues David L. Kaplan, David H. Lee, Elena V. Rybak-Akimova and David R. Walt from Tufts University will acquire a two channel 500 MHz NMR spectrometer with pulsed field gradients for use by multiple investigators spanning three departments and two schools on the Medford campus of the University. The NMR spectrometer will enable research by a diverse group of researchers in the chemical and biological sciences ranging from characterization of organometallic/protein complexes and cellulose polymers, to the analysis of non-natural fluorinated peptides and post-translational modifications of proteins that direct supramolecular self-assembly.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/inorganic chemistry and biochemistry.
