MRI: Acquisition of a 400 MHz Nuclear Magnetic Resonance (NMR) Spectrometer at Idaho State University

该奖项由主要研究仪器、化学研究仪器计划和既定的激励竞争性研究计划(EPSCoR)支持。爱达荷州立大学正在购买一台配备自动换样器的400 MHz核磁共振光谱仪，以支持安德鲁·霍兰德、雷内·罗德里格斯、卡琳·伊维利亚、考特尼·詹金斯、斯里纳特·帕希坎蒂和其他同事。这种光谱仪允许在各种领域进行研究，例如那些加速具有重大经济意义的化学反应的领域，以及允许研究具有生物相关性的物种。总体而言，核磁共振波谱是化学家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。该仪器是化学和生物化学方面学生，包括代表人数不足的学生和残疾学生的教学、研究和研究培训的组成部分。核磁共振光谱仪的获奖旨在加强各级的研究和教育。它特别有利于研究生长在或能耐盐的微生物(嗜盐微生物)产生的多肽的结构，以及制备从氨基酸L-丝氨酸衍生的手性氨基丁烯内酯合成子。该仪器还用于研究与制造相关的富含地球的半导体纳米材料的分子前体。此外，它还提供了有助于分析和修改多硫化物材料以及替换新的金属和氢键有机骨架中的硫族的信息。该分光计还被用来表征在山间西部本土植物中发现的天然产品。这一奖项反映了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 supported by the Major Research Instrumentation, the Chemistry Research Instrumentation programs and the Established Program to Stimulate Competitive Research (EPSCoR). Idaho State University is acquiring a 400 MHz nuclear magnetic resonance (NMR) spectrometer equipped with an automatic sample changer to support Professors Andrew Holland, Rene Rodriguez, Caryn Evilia, Courtney Jenkins, Srinath Pashikanti and other colleagues. This spectrometer allows research in a variety of fields such as those that accelerate chemical reactions of significant economic importance, 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 students in chemistry and biochemistry including underrepresented students and those with disabilities. The award of the NMR spectrometer is aimed at enhancing research and education at all levels. It especially facilitates studies of the structures of peptides produced by microorganisms that grow in or can tolerate saline conditions (halophiles) and for preparing chiral aminobutenolide synthons derived from the aminoacid L-serine. The instrumentation is also used in investigations of molecular precursors for earth-abundant semiconducting nanomaterials of relevance to manufacturing. In addition, it provides information to aid analyses and modifications of polysulfide materials and for replacing chalcogens in new metal and hydrogen bonding organic frameworks. The spectrometer is also used to characterize natural products found in the indigenous flora of the intermountain west.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.
