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 at the University of Texas, Austin, to acquire 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) Solid-state characterizations of new semiconductors and ceramic composities 2) Studies of solid-state/molecular microstructures using 13C-CPMAS NMR 3) The SP allotrope of carbon 4) Use of solid-state NMR with intractable polymers.

现代固态核磁共振波谱为化学家提供了研究材料物理和化学性质的最强大的工具之一。固体核磁共振技术可以获得从生物聚合物、树脂、煤和液晶等各种材料的结构和动力学的基本知识。固体核磁共振研究通常是对使用溶液核磁共振和X射线分析进行的研究的补充。对于从事前沿研究的化学家来说，获得固态核磁共振正迅速变得至关重要。化学仪器计划的这一奖项将帮助德克萨斯大学奥斯汀分校化学系获得一台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：1)新半导体和陶瓷成分的固态表征2)用~(13)C-CPMAS核磁共振研究固体/分子结构；3)碳的SP同素异形体；4)固体核磁共振在难熔聚合物中的应用。
