Switch Angle Sample Spinning Probes and High Resolution Dipolar Recoupling with Quadrupolar Nuclei

该奖项由化学学部化学测量与成像项目资助，西弗吉尼亚大学的Terry Gullion教授和他的本科生和研究生研究人员将开发新的固态核磁共振（NMR）方法，用于测量自旋为1/2的原子核和四极原子核之间的偶极耦合。仔细测量原子核间的耦合可以得到化学物质中原子间距离的准确信息。Gullion教授将通过开发新型样品纺丝方法以及设计和建造新型探针来实现这一目标。核磁共振波谱是一种重要的物理化学方法，可以提供精确的化学和结构信息。Gullion教授和他的学生研究人员将开发的方法将使科学家能够测量难以通过实验处理的原子核之间的核间距离。这项工作有可能为生物和材料科学开辟新的前景，在这些领域，从这些类型的实验中获得的信息对于将结构与功能联系起来至关重要。参与本计画的本科生和研究生，将获得建构核磁共振实验硬件的有用经验。作为这项工作的一部分，Gullion教授还将为科学界成员举办核磁共振硬件（传输线探针）建设研讨会。

In this award, funded by the Chemical Measurement and Imaging Program of the Division of Chemistry, Professor Terry Gullion of West Virginia University and his undergraduate and graduate student researchers will be supported to develop new solid-state nuclear magnetic resonance (NMR) methods for measuring dipolar coupling between nuclei with spin = 1/2 and quadrupolar nuclei. Careful measurement of the coupling between nuclei can yield accurate information on the distance between atoms in chemical materials. Professor Gullion will do this through development of novel sample spinning methods in conjunction with the design and construction of new kinds of probes.Nuclear magnetic resonance spectroscopy is an important physicochemical method that gives precise chemical and structural information. The methods that Prof. Gullion and his student researchers will develop will enable scientists to measure inter-nuclear distances between nuclei that are difficult to deal with, experimentally. The work has the potential to open up new vistas in biological and materials science where the kind of information that can be obtained from these types of experiments is critical in order to relate structure with function. The undergraduate and graduate students working on this project will gain useful experience in building hardware for NMR experiments. As part of this work, Prof. Gullion will also conduct workshops on NMR hardware (transmission line probe) construction for members of the scientific community.
