Acquisition of Solid-State Probes and Electronics for an Existing NMR Spectrometer

在化学研究仪器和设施：多用户计划(CRIF：MU)的支持下，雷诺内华达大学化学系将翻新一台核磁共振(核磁共振)光谱仪，并对其进行升级，为该大学提供现代固态核磁共振能力。新的仪器将用于广泛的研究项目，包括合成不寻常的多环芳烃，研究多肽和蛋白质的三维固态结构，催化剂的研究，燃料电池膜的分析，以及功能性超分子聚合物的表征。核磁共振光谱学是化学中任何分子合成学科中广泛使用的分析工具。光谱是通过检测原子的核自旋性质引起的能级之间的跃迁而获得的，它提供了关于分子和材料中原子的排列和连接性的信息。这些数据使研究人员能够识别未知物质并确定它们的结构。这种特殊的仪器将分析固体状态的物质，从而提供关于各种不溶物质的有价值的结构信息。该仪器还将允许将固态核磁共振实验纳入本科课程。这种核磁共振波谱仪将被化学系的其他人、化学和材料工程系的研究人员以及全州的研究人员使用。作为内华达州唯一普遍可用的固态核磁共振光谱仪，该仪器预计将对该州的研究和教育产生广泛影响。

With support from the Chemistry Research Instrumentation and Facilities: Multi-User program (CRIF:MU), the Department of Chemistry at the University of Nevada, Reno will refurbish a nuclear magnetic resonance (NMR) spectrometer and upgrade it to provide modern solid-state NMR capabilities to the University. The new instrumentation will be employed in a wide variety of research projects including the synthesis of unusual polycyclic aromatic hydrocarbons, investigations of the three dimensional solid-state structure of peptides and proteins, studies of catalysts, analysis of fuel cell membranes, and the characterization of functional supramolecular polymers. NMR spectroscopy is a widely used analytical tool in any molecular-synthetic discipline in chemistry. Spectra, obtained by detecting transitions between energy levels arising from the nuclear spin properties of atoms, provide information on the arrangement and connectivity of atoms in molecules and materials. These data enable researchers to identify unknown substances and to determine their structures. This particular instrument will analyze substances in the solid state thereby providing valuable structural information on a variety of insoluble materials. The instrumentation will also allow the incorporation of solid-state NMR experiments into undergraduate courses. This NMR spectrometer will be used by others in the Chemistry Department, investigators in the Chemical and Material Engineering Departments and by researchers throughout the state. As the only generally available solid-state NMR spectrometer in Nevada, the instrument is expected to have a broad impact on research and education in the state.
