MRI: Acquisition of a 400 MHz Nuclear Magnetic Resonance (NMR)Spectrometer to Enable Material Science Research

该奖项由主要研究仪器和化学研究仪器计划支持。加州伯克利大学正在购买一台400 MHz核磁共振（NMR）光谱仪，该光谱仪配备有1.3 mm和3.2 mm固态探针、扩散探针和显微成像功能，以支持Jeffrey Reimer、Hasan Celik和其他同事。该光谱仪可用于各种领域的研究，例如加速具有重要经济意义的化学反应，电池，以及允许研究生物相关物种。一般来说，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，并研究溶液或固态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。该仪器是该机构和附近大学的化学和生物化学本科生和研究生的教学、研究和研究培训的一个组成部分，授予NMR光谱仪的目的是加强各级的研究和教育。它特别影响了研究多孔和软材料的分析方法的光谱发展。该仪器还用于研究超分子材料，通常称为金属有机框架（MOFs），能够吸收和交换气体。此外，它还为开发锂电池用固体聚合物电解质提供了信息。NMR光谱仪还用于通过优化MOF合成的化学性质来确定相关材料的序列，以建立化学功能性和扩散速率之间的关系，以及底物吸收和释放的动力学。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值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 supported by the Major Research Instrumentation and the Chemistry Research Instrumentation programs. The University of California Berkeley is acquiring a 400 MHz nuclear magnetic resonance (NMR) spectrometer equipped with 1.3 mm and 3.2 mm solid-state probes, a diffusion probe, and micro-imaging capabilities to support Jeffrey Reimer, Hasan Celik, and other colleagues. This spectrometer allows research in a variety of fields such as those that accelerate chemical reactions of significant economic importance, batteries, as well as permitting study of biologically relevant species. In general, 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 is an integral part of teaching as well as research and research training of undergraduate and graduate students in chemistry and biochemistry at this institution and nearby universities.The award of the NMR spectrometer is aimed at enhancing research and education at all levels. It especially impacts spectroscopic development of analytical methods to investigate porous and soft materials. The instrumentation is also used for studying supramolecular materials commonly known as MOFs (metal-organic frameworks) capable of absorbing and exchanging gases. In addition, it provides information for developing solid polymer electrolytes for lithium batteries. The NMR spectrometer is also used to sequence dependent materials by optimizing the chemistry of MOF synthesis to establish the relationship between chemical functionality and diffusion rates, and kinetics of uptake and release of substrates.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.
