MRI: Acquisition of a 400 MHz Nuclear Magnetic Resonance Spectrometer for the Advancement of Research and Teaching at Texas A&M International University

得克萨斯农工大学(TAMUI)的Alfred Addo-Mensah教授及其同事Anju Gupta、Eugenio Jaramillo、庆文和James Cohen将获得由化学研究仪器和设施(CRIF)计划共同资助的主要研究仪器计划颁发的这一奖项，该仪器将安装在TAMUI，但也可以进入拉雷多社区学院(LCC)。该奖项旨在加强所有层面的研究和教育，特别是在下列领域：(A)水溶液中基于联吡啶的多价大环碳水化合物受体的设计、合成、表征和结合研究；(B)紫草科植物中萘醌类化合物的进化模式、鉴定和表征；(C)含有过渡金属离子的分子筛的研究；以及(D)发光聚合物的设计和合成。核磁共振波谱是化学家可用于阐明分子结构的最强大的工具之一。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合成有机/无机化学、材料化学和生物化学产生影响。这一工具将成为这两个少数群体服务机构教学和研究的一个组成部分，这将增加大批代表不足的学生获得现代工具的机会。

With this award from the Major Research Instrumentation Program that is co-funded by the Chemistry Research Instrumentation and Facilities (CRIF) Program, Professor Alfred Addo-Mensah from Texas A&M International University (TAMUI) and colleagues Anju Gupta, Eugenio Jaramillo, Qingwen Ni and James Cohen will acquire a 400 MHz NMR spectrometer to be housed at TAMUI but also accesible to Laredo Community College (LCC). This award is aimed at enhancing research and education at all levels, especially in areas such as (a) design, synthesis, characterization and binding studies of multivalent bipyridine based macrocyclic carbohydrate receptors in aqueous solutions; (b) evolutionary patterns, identification, and characterization of naphthoquinones in the plant family boraginaceae; (c) study of molecular sieves containing transition metal ions; and (d) design and synthesis of light-emitting polymers.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 at both of these minority serving institutions, which will increase access to modern instrumentation to a large number of underrepresented students.
