这项研究将集中在一个全面的计划，探讨 非溶剂化（RLi）n超聚集体的流动动力学，Li自旋计数 在（RLi）n团簇中，离子对内的离子-离子重取向模式， 可变的离域性，由内部的立体化学引起 锂的溶剂化，结构的空间效应，共轭二价阴离子盐， Li-C、C双键配位与化学、核磁共振 液晶介质中离子对的共振（NMR）性质。 的 实验工作也将通过计算得到补充。与此 更新奖，有机动力学计划是支持研究 吉迪恩·A博士俄亥俄州化学系的Fraenkel说， 大学 Fraenkel教授将把工作重点放在确定 有机锂化合物溶液结构的核磁共振研究 共振（NMR）技术。 多用途和有用的合成化学 这类化合物所表现出的这种结构工作， 重要.

This research will focus on a comprehensive program which probes the fluxional dynamics of unsolvated (RLi)n hyperaggregates, Li spin counting in (RLi)n clusters, modes of ion-ion reorientation within ion pairs, variable delocalization resulting from stereochemistry of internal solvation of Li, steric effects of structure, conjugated dianion salts, Li-C,C double bond coordination and chemistry and Nuclear Magnetic Resonance (NMR) properties of ion pairs in liquid crystal medium. The experimental work will also be complemented by calculations. With this renewal award, the Organic Dynamics Program is supporting the research of Dr. Gideon A. Fraenkel of the Department of Chemistry at Ohio State University. Professor Fraenkel will focus his work on determining the solution structures of organolithium compounds using Nuclear Magnetic Resonance (NMR) techniques. The versatile and useful synthetic chemistry shown by this class of compounds makes this structural work even more important.
