With support from the Major Research Instrumentation (MRI) Program, the Department of Chemistry at the University of Nevada in Reno will acquire a 400 MHz nuclear magnetic resonance (NMR) Spectrometer and upgrade an existing 500 MHz multinuclear NMR. This equipment will enable researchers to carry out studies on a) the design and synthesis of complex organic molecules; b) the synthesis, characterization, binding and luminescent properties of metallocryptands; c) the synthesis, structure and reactivity of organometallic complexes with emphasis on those applicable to aqueous/biphasic catalysis; d) the designed synthesis of one-dimensional benzenoid nanostructures; e) the stereochemistry of bilirubin and its carboxylate anions in organic and aqueous media by heteronuclear NMR; and f) the behavior of transition and main group metals in biological systems. 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 chemistry, nanoscience and biochemistry.

在主要研究仪器（MRI）计划的支持下，位于里诺的内华达州大学化学系将获得一台400 MHz核磁共振（NMR）光谱仪，并升级现有的500 MHz多核NMR。这一设备将使研究人员能够进行以下研究：（a）复杂有机分子的设计和合成;（B）双隐配体的合成、表征、结合和发光特性;（c）有机金属配合物的合成、结构和反应性，重点是适用于水/两相催化的有机金属配合物;（d）一维苯型纳米结构的设计合成; e）胆红素及其羧酸根阴离子在有机和水介质中的立体化学; f）过渡金属和主族金属在生物系统中的行为。 核磁共振（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，并研究溶液中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。这些NMR研究的结果将对合成有机化学、纳米科学和生物化学产生影响。
