Purchase of a Solid State NMR Spectrometer

这份来自化学研究仪器和设施（CRIF）项目和主要研究仪器（MRI）项目的合同将使克拉克大学化学学院获得一台400兆赫的固态核磁共振（NMR）光谱仪。这将加强教师在许多领域的研究，包括1)通过氙-129核磁共振研究合成膜和纳米多孔材料中的气体状态；2)聚合物体系中的平移扩散；3)利用魔角纺丝实验研究聚合物的结构与动力学；4)一维和二维固体重定向动力学的线形研究。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 (CRIF) Program and the Major Research Instrumentation (MRI) Program will enable the School of Chemistry at Clark University to acquire a 400 MHz solid state Nuclear Magnetic Resonance (NMR) spectrometer. This will enhance faculty research in a number of areas including studies on 1) the state of gases in synthetic membrane and nanoporous materials by xenon-129 NMR; 2) translational diffusion in polymeric systems; 3) structure and dynamics in polymers using magic angle sample spinning experiments; and 4) one and two-dimensional solid state line shape studies of reorientational dynamics. 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.
