This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With support from the Chemistry Research Instrumentation and Facilities:Multiuser program (CRIF:MU), the Department of Chemistry at the University of Texas at Arlington (UTA) will upgrade a 500 MHz nuclear magnetic resonance (NMR) spectrometer with a new console and broadband probe and obtain two sample carousels (for a 300 MHz and the 500 MHz spectrometer). The research activity to be supported by this instrument spans areas in synthetic organic, inorganic, physical organic, and polymer chemistry. These include the study of (i) multi-metal complexes for light harvesting, (ii) metal complexes of new fluorinated poly(pyrazolyl)borate ligands with unusual catalytic and luminescent properties, (iii) polymeric materials with enhanced electrical conductivity, possible superconductivity, and electro- and photo luminescent properties, (iv) the total synthesis of bioactive alkaloids, (v) the development of new organocatalysts, and (vi) synthetic methods development. NMR spectroscopy is a powerful tool essential for progress in modern chemical research. NMR spectra enable researchers to study how molecules react and to identify reaction products and unstable reaction intermediates. Structural information on how the atoms are connected in the molecules under study is obtained from observing transitions between energy levels arising from the nuclear magnetic spin properties of atoms. The instruments will be used to support research projects of undergraduate, graduate and postdoctoral students at UTA and train them in the use of state-of-the-art instrumentation. UTA will pilot a program with Tarrant County College to allow students in a sophomore organic lab to obtain and interpret data from their experiments.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。在化学研究仪器和设施：多用户计划（CRIF:MU）的支持下，德克萨斯大学阿灵顿分校（UTA）化学系将用新的控制台和宽带探头升级500 MHz核磁共振（NMR）光谱仪，并获得两个样品旋转带（用于300 MHz和500 MHz光谱仪）。该仪器支持的研究活动涵盖合成有机、无机、物理有机和聚合物化学等领域。这些研究包括：(i)用于光收集的多金属配合物，（ii）具有不同寻常的催化和发光特性的新型氟化聚（吡唑基）硼酸盐配体的金属配合物，（iii）具有增强导电性、可能的超导性以及电和光发光特性的聚合材料，（iv）生物活性生物碱的全合成，(v)新的有机催化剂的开发，以及（vi）合成方法的开发。核磁共振波谱是现代化学研究进步必不可少的有力工具。核磁共振光谱使研究人员能够研究分子如何反应，并识别反应产物和不稳定的反应中间体。关于所研究分子中原子如何连接的结构信息，是通过观察原子的核磁自旋特性引起的能级之间的跃迁而获得的。这些仪器将用于支持UTA本科生，研究生和博士后的研究项目，并培训他们使用最先进的仪器。犹他大学将与塔兰特县学院（Tarrant County College）试行一个项目，允许大二有机实验室的学生从实验中获取和解释数据。
