Acquisition of a 500 MHz NMR Spectrometer

获得该奖项后，Krishna Kumar及其同事、塔夫茨大学的David L.Kaplan、David H.Lee、Elena V.Rybak-Akimova和David R.Walt将获得一台具有脉冲场梯度的双通道500 MHz核磁共振波谱仪，供该大学梅德福德校区三个系和两个学院的多名研究人员使用。核磁共振波谱仪将使化学和生物科学领域的不同研究人员能够进行研究，范围从有机金属/蛋白质络合物和纤维素聚合物的表征，到非天然氟化肽的分析和指导超分子自组装的蛋白质的翻译后修饰。核磁共振波谱是化学家可用于阐明分子结构的最强大的工具之一。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/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.
