摘要:

核磁共振中分子内与分子间多量子相干已得到充分的发展和广泛的使用. 为深入系统地比较研究两种多量子相干的物理机理与性质及其潜在的应用,本文总结近年来相关研究的前沿,首先系统地论述了产生这两种多量子相干的基础-偶极耦合-的作用机理,然后再分别描述基于分子内偶极耦合的分子内多量子相干和基于分子间偶极耦合的分子间多量子相干的原理、性质、及其在化学、生物等领域中的应用. 

Abstract:

Great progresses have been made in the past decades in understanding intra- and inter-molecular multiple-quantum coherences (MQCs) and developing their applications in nuclear magnetic resonance. To develop further applications for MQCs, it is useful to understand their physical bases and ways of practical implementation. In this review, the principles of dipolar coupling are described firstly. Comprehensive descriptions of MQCs based on intra- and inter-molecular dipolar coupling are then summarized, respectively. Finally, the applications of intra- and inter-molecular MQCs in chemistry and biomedicine are presented.

Key words: NMR, dipolar coupling, inter-molecular multiple-quantum coherences (MQC), intra-molecular MQCs, MRI
