Purchase of a High Field Nuclear Magnetic Resonance Spectrometer

这份来自化学研究仪器和设施项目的合同将帮助西南德克萨斯州立大学化学系获得一台300 MHz核磁共振光谱仪和工作站。该设备将加强以下几个领域的研究：(1)车芳烃、硼和钒化学；(2)含有3,3-二（三氟甲基）-1,3-二氢-2,1-苯并恶唑环的新型聚合物；(3)耐原子氧烧蚀的聚合物；(4)铁基团化学；(5)异氰酸酯的新采样和分析方法；(6)细菌多糖三级结构。核磁共振（NMR）波谱是化学家用来阐明分子结构的最有力的工具。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。获得最先进的核磁共振光谱是必不可少的化学家谁正在进行前沿研究。这些核磁共振研究的结果在聚合物、催化和生物学等领域是有用的。

This award from the Chemistry Research Instrumentation and Facilities Program will assist the Department of Chemistry at Southwest Texas State University aquire a 300 MHz NMR spectrometer and workstation. This equipment will enhance research in a number of areas including the following: (1) calixarene, boron and vanadium chemistry (2) novel polymers containing the 3,3-bis(trifluormethyl)-1,3-dihydro-2,1-benzoxasilole ring (3) polymers resistant of atomic oxygen ablation (4) siderophore chemistry (5) new sampling and analysis methods for isocyanates, and (6) bacterial polysaccharide tertiary structure. 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, 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 spectrometry is essential to chemists who are carrying out frontier research. The results from these NMR studies are useful in the areas such as polymers, catalysis, and in biology.
