Abstract

The development of (6)Li diffusion-ordered NMR spectroscopy (DOSY) is reported. This technique is applied to (6)Li organometallic complexes. (6)Li DOSY provides a facile means of identification of peaks in the (6)Li spectrum, as well as evidence of mixed aggregates based on relative diffusion coefficients. (6)Li data is correlated to (1)H diffusion experiments through (6)Li{(1)H} HOESY and/or (1)H{(6)Li} HMBC experiments to obtain formula weight information of Li aggregates.

摘要

报道了（6）Li 扩散排序核磁共振波谱（DOSY）的发展。该技术应用于（6）Li 有机金属配合物。（6）Li DOSY 为（6）Li 光谱中的峰的识别提供了一种简便的方法，并且基于相对扩散系数为混合聚集物提供了证据。通过（6）Li{(1)H} HOESY 和/或（1）H{(6)Li} HMBC 实验将（6）Li 数据与（1）H 扩散实验相关联，以获得 Li 聚集物的分子量信息。
