With this award from the Chemistry Research Instrumentation and Facilities (CRIF) Program, the Department of Chemistry at Texas A&M University will acquire a Solid-State 400 MHz Multinuclear NMR Spectrometer. This equipment will enable researchers to carry out research on a) surface-grafted gels and encapsulated catalysts; b) metal phosphonate chemistry; c) copolymerization of CO2 and epoxides to provide polycarbonates; d) extended arrays with phosphine ligands based on tetrathiafulvalene; e) chemistry of polyfunctional Lewis acids; and f) guest-host interactions and local structure in porous solids. Nuclear Magnetic Resonance (NMR) spectroscopy is the most powerful tool 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 fundamental synthetic organic chemistry and the development of novel polymers.

得克萨斯农工大学化学系将获得化学研究仪器和设施(CRIF)计划颁发的这一奖项，从而获得一台400 MHz多核固体核磁共振光谱仪。该设备将使研究人员能够开展以下方面的研究：a)表面接枝凝胶和包埋催化剂；b)金属膦化学；c)二氧化碳和环氧化物的共聚，以提供聚碳酸酯；d)基于四硫富瓦烯的膦配体的扩展阵列；e)多官能团Lewis酸的化学；f)多孔固体中的客体-宿主相互作用和局部结构。核磁共振波谱是化学家用来解释分子结构的最有力的工具。它被用来识别未知物质，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。这些核磁共振研究的结果将对基础合成有机化学和新型聚合物的开发产生影响。
