Modern solid-state Nuclear Magnetic Resonance (NMR) spectroscopy offers the chemist one of the most powerful tools available for the study of the physical and chemical properties of materials. Fundamental knowledge of structure and dynamics of materials as diverse as biopolymers, resins, coals, and liquid crystals is accessible by solid-state NMR techniques. Solid-state NMR studies often complement those carried out using solution NMR and X-ray analysis. Access to solid-state NMR is rapidly becoming essential to chemists carrying out frontier research. This award from the Chemical Instrumentation Program will help the Department of Chemistry of the University of California, San Diego, to construct a high-field NMR spectrometer suitable for carrying out solid-state NMR studies. The areas of chemical research that will be enhanced by the acquisition include the following. 1) Studies of spin relaxation and molecular motion in solids 2) Ligand and solvate dynamics of solid-state transition metal complexes.

现代固态核磁共振（NMR）光谱学为化学家研究材料的物理和化学性质提供了最有力的工具之一。通过固态核磁共振技术，可以获得生物聚合物、树脂、煤和液晶等多种材料的结构和动力学的基本知识。固态核磁共振研究通常是对溶液核磁共振和x射线分析的补充。获得固态核磁共振正迅速成为化学家进行前沿研究的必要条件。这份来自化学仪器项目的奖金将帮助加州大学圣地亚哥分校化学系建造一个适合进行固态核磁共振研究的高场核磁共振光谱仪。此次收购将加强的化学研究领域包括以下几个方面。1)固体中自旋弛豫和分子运动的研究2)固态过渡金属配合物的配体和溶剂动力学。
