Purchase of a Solid State NMR Spectrometer

化学研究仪器和设施 (CRIF) 计划和主要研究仪器 (MRI) 计划授予的这一奖项将使克拉克大学化学学院能够获得一台 400 MHz 固态核磁共振 (NMR) 波谱仪。 这将加强教师在多个领域的研究，包括 1) 通过氙 129 NMR 分析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) 使用魔角样品纺丝实验研究聚合物的结构和动力学； 4）重定向动力学的一维和二维固态线形研究。 核磁共振 (NMR) 光谱是化学家阐明分子结构的最强大工具。 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。对于进行前沿研究的化学家来说，获得最先进的核磁共振波谱分析至关重要。这些 NMR 研究的结果可用于聚合物、催化和生物学等领域。

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.
