Development of Multipolar Zero-Field NMR Spectroscopy ethods

该奖项是Chmelka博士化学博士后奖学金的启动资助增量。该工作将通过仪器改进发展多极零场核磁共振的方法。样品穿梭时间将减少，从而使研究具有更短的自旋-晶格弛豫时间的系统成为可能。偶极偶联的可用范围将扩大到50千赫，以便研究固体有机化合物。该仪器将应用于部分有序体系中分子团簇的研究。核磁共振波谱（NMR）是测定分子结构的重要方法。核磁共振方法将发展到研究固体系统对理解沸石催化的重要性。这些系统具有重要的商业价值。

This award is the starter grant increment of Dr. Chmelka's Postdoctoral Fellowship in Chemistry. The work will develop the methodology of multipolar zero-field NMR through instrumental improvements. Sample shuttling times will be reduced so as to make it possible to study systems with shorter spin-lattice relaxation times. The range of accessible dipolar couplings will be extended to 50 kHz so that solid organic compounds may be studied. The new instrumentaion will be applied to the study of molecular clusters in partially ordered systems. %%% Nuclear magnetic resonance spectroscopy, NMR, is an important method for determining molecular structure. The NMR approach will be developed to study solid systems of importance to understanding catalysis in zeolites. These are systems of great commercial importance.
