Purchase of a Solid State 300MHz NMR Spectrometer

化学研究仪器计划的这一奖项将帮助纽约州立大学化学系--斯托尼布鲁克获得一台固态300 MHz NMR光谱仪，该光谱仪将用于化学、材料科学和地球空间科学的以下领域的研究调查：（1）使用双共振和三共振NMR研究基本探针分子和氢氟烃在表面上的吸收，以及探测无序连续固体如氟快离子导体和氟氧化物中的离子分布;（2）研究硅酸盐玻璃和液体中的形态，以便将结构信息与热力学模型的开发相结合，以预测在高温高压下地质上重要的成分的相平衡;（3）研究金属蛋白中金属-半胱氨酸中心的模型;（4）研究II型糖尿病中淀粉样纤维形成的分子基础;（5）将NMR与衍射数据紧密结合，以解决矿物学和沸石化学中的无序问题。 核磁共振（NMR）光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。 对于从事前沿研究的化学家来说，使用最先进的NMR光谱分析技术是必不可少的。 这些NMR研究的结果在聚合物和催化以及生物学等领域都很有用。

This award from the Chemistry Research Instrumentation Program will help the Department of Chemistry at the SUNY--Stony Brook acquire a solid state 300 MHz NMR spectrometer which will be used in research investigations in the following areas of chemistry, material science, and earth space sciences: (1) to study the absorption of basic probe molecules and hydrofluorocarbons on surfaces, using double and triple resonance NMR, and to probe the distributions of ions in disordered continuous solids such as fluorine fast-ion conductors and oxy-fluorides; (2) to investigate speciation in silicate glasses and liquids, in order to couple structural information with the development of thermodynamic models for prediction of phase equilibria of geologically important compositions at elevated pressures and temperatures; (3) to investigate models for metal-cysteine centers in metalloproteins; (4) to study the molecular basis of amyloid fibril formation in type-II diabetes; and (5) to use NMR in close combination with diffraction data, to tackle problems of disorder in mineralogy and zeolite chemistry. 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 and catalysis, and in biology.
