This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).With this award from the Major Research Instrumentation (MRI) program Professor Nancy S. Mills and colleagues Jessica Hollenbeck, Laura Hunsicker-Wang and Adam R. Urbach from the Department of Chemistry at Trinity University will acquire a 500 MHz NMR spectrometer equipped with a broad band probe. The instrument will be used to support research activities such as: 1) probing the conformational flexibility of designed ankyrin-repeat proteins; 2) studying the cooperation of intermolecular interactions within the framework of a rigid DNA duplex in complexes containing polyamide ligands; 3) examination of the pH dependence of the redox behavior of Rieske proteins through chemical modification of potential titratable groups to characterize modified amino acids; and 4) evaluation of interactions of lithium counterions with antiaromatic dianions.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/inorganic chemistry, materials chemistry and biochemistry. This instrument will be an integral part of teaching as well as research.

该奖项是根据2009年的《美国复苏与再投资法》（公法111-5）资助的。与主要研究工具（MRI）计划教授南希·米尔斯（Nancy S.该仪器将用于支持研究活动，例如：1）探测设计的Ankyrin-Repeat蛋白的构象灵活性； 2）研究含有聚酰胺配体的复合物中刚性DNA双链体框架内分子间相互作用的合作； 3）检查Rieske蛋白的氧化还原行为的pH依赖性通过化学修饰潜在的可滴定组的化学作用，以表征改良的氨基酸； 4）评估锂柜台与抗乳房乳房的相互作用。核磁共振（NMR）光谱是化学家可用的最强大工具之一，用于阐明分子结构。它用于识别未知物质，以表征分子中原子的特定排列，并研究溶液中分子之间相互作用的动力学。对于正在进行边境研究的化学家来说，获得最先进的NMR光谱仪至关重要。这些NMR研究的结果将对合成有机/无机化学，材料化学和生物化学产生影响。该工具将是教学和研究的组成部分。
