MRI: Acquisition of 400 MHz NMR Spectrometer for Chemistry Research

该奖项由主要研究仪器和化学研究仪器项目以及既定的激励竞争性研究计划共同支持。格林内尔学院正在为一台带有扩散探头的400 MHz核磁共振(核磁共振)光谱仪购买升级版的控制台，以支持安德鲁·莫布利教授及其同事埃里克·莱根斯、莱斯利·莱昂斯、莫莉·麦金尼斯和斯蒂芬·西克的研究。该仪器促进了有机化学、有机金属化学、天然产物和材料科学领域的研究。总的来说，核磁共振波谱是化学家用来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，表征分子中原子的特定排列，并研究分子在溶液或固体中相互作用的动力学。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。该仪器加强了格林内尔学院多个系的各级学生的教育、研究和教学努力，并提供了在附近机构使用的便利条件。该仪器还使研究小组能够积极招收来自不同背景的学生，并扩大矿化群体在科学中的代表性。核磁共振波谱仪的获奖旨在加强各级研究和教育，特别是在有机化学、有机金属化学、天然产物和材料科学等领域。该仪器影响的研究重点是促进对异双金属络合物和离子在电解液和石墨网中传输的理解。具体地说，该仪器将用于广泛的项目，如：1)钨和铂的锡氢化物络合物的异核NOE和核磁共振弛豫研究，2)天然产物lugdunin构象行为的详细变温结构研究，3)锂离子和钠电池电解液中溶剂与金属离子相互作用的结构测定，4)Li，Na和Ln离子在石墨化悬浮液中的自扩散研究，以及5)J耦合研究，以确定新型查尔酮的构型和溶液构象。400 MHz核磁共振波谱仪支持的研究项目可能会在能量储存和生物技术等领域产生影响。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This award is jointly supported by the Major Research Instrumentation and the Chemistry Research Instrumentation Programs, and the Established Program to Stimulate Competitive Research. Grinnell College is acquiring an upgraded console for a 400 MHz nuclear magnetic resonance (NMR) spectrometer with a diffusion probe to support the research of Professor Andrew Mobley and colleagues Erick Leggans, Leslie Lyons, Molly MacInnes, and Stephen Sieck. This instrument facilitates research in the areas of organic chemistry, organometallic chemistry, natural products, and material science. In general, 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 or in the solid state. Access to state-of-the-art NMR spectrometers is essential to chemists who are carrying out frontier research. This instrument enhances the educational, research, and teaching efforts of students at all levels in many departments at Grinnell College as well as provides accessibility for use at nearby institutions. The instrument also enables the research groups to work actively to recruit students from a diverse background and broaden the representation of minoritized groups in the sciences.The award of the NMR spectrometer is aimed at enhancing the research and education at all levels, especially in areas such as organic chemistry, organometallic chemistry, natural products, and material science. The instrument impacts research focused on advancing the understanding of heterobimetallic complexes and ion transport in electrolytes and graphitic networks. Specifically, the instrument will be used in a wide spectrum of projects such as: 1) heteronuclear NOE and NMR-relaxation studies of Sn hydride complexes of W and Pt, 2) detailed variable temperature structural studies of the conformational behavior of the natural product lugdunin, 3) structural determination of the interaction between solvent and metal ions in electrolytes for Li-ion and Na batteries, 4) self-diffusion studies of Li, Na, and Ln ions in graphitic suspensions, and 5) J-coupling studies to determine the configuration and solution state conformation of novel chalcones. The research projects to be enabled by the 400MHz NMR spectrometer could lead to impacts in the fields such as energy storage and biotechnology.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
