CAREER: Study of Electrically Aligned Molecules with NMR

加州大学戴维斯分校的马修·奥古斯丁教授是由CAREER基金资助的实验物理化学项目。他将开发一种新的核磁共振（NMR）方法，用于测定溶液中分子的结构，其中对样品施加电场。这破坏了溶液的各向同性性质，并引入了电子和距离相关的各向异性线分裂到核磁共振光谱。他有初步的结果来证明这种效应。额外的信息使结构预测达到前所未有的精度。多重键合的有机金属化合物和DNA以及DNA/蛋白质复合物将被研究。奥古斯丁教授计划修改量子力学和新生化学课程，以满足加州大学戴维斯分校研究生和本科生的不同教育需求。他还计划通过高中化学奥林匹克竞赛和美国化学学会萨克拉门托分会向公众宣传核磁共振。磁共振是一种方法，正在迅速成为一种标准的化学工具，用于确定分子的结构，如蛋白质和DNA。它是更广为人知的医学诊断——磁共振成像（MRI）的化学版本。奥古斯丁教授的工作基于更复杂的实验装置，这将提高这类数据的质量，并将使科学家能够更准确地确定化学和生物学上重要分子的结构。奥古斯丁教授在教育方面的努力将提高量子力学在各个层次的大学课程中的整合程度。第二项努力将寻求教育公众有关磁共振方法。

Professor Matthew Augustine of the University of California at Davis is funded by a CAREER grant in the Experimental Physical Chemistry program. He will develop a new Nuclear Magnetic Resonance (NMR) method for structure determination of molecules in solution in which an electric field is applied to the sample. This destroys the isotropic nature of the solution and introduces electronically and distance dependent anisotropic line splittings to an NMR spectrum. He has preliminary results demonstrating the effect. The additional information allows structure predictions of unprecedented accuracy. Multiply bonded organometallic compounds and DNA and DNA/protein complexes are to be studied. Professor Augustine plans to modify quantum mechanics and freshman chemistry courses to meet diverse educational needs of graduate and undergraduate students at UC Davis. He also plans to educate the public about NMR through the High School Chemistry Olympiad and the Sacramento section of the American Chemical Society.Magnetic resonance is a method that is rapidly becoming a standard tool in chemistry for the determination of structures of molecules such as proteins and DNA. It is the chemical version of the more widely known medical diagnostic, Magnetic Resonance Imaging (MRI). Professor Augustine's work based on a more sophisticated experimental setup will improve the quality of this type of data and will allow scientists to make more accurate structure determinations of chemically and biologically important molecules. Professor Augustine's educational efforts will improve the integration of quantum mechanics into university coursework at all levels. A second effort will seek to educate the public about magnetic resonance methods.
