摘要

我们将耗散开放系统的林德布拉德方程用于研究双自旋系统中多量子（MQ）核磁共振相干性的弛豫。我们选择了两个双自旋系统的例子。其中一个是汉贝格石单晶体中的人字形质子链，其取向使得链内两个双极耦合常数中的一个变为零。这样，质子链就由孤立的成对自旋组成，每对自旋通过偶极-偶极相互作用耦合在一起。双自旋系统的第二个例子是石膏单晶体，其中的质子属于水分子。研究了不同 MQ NMR 实验准备时间下的 MQ NMR 动态弛豫。

Lindblad Relaxation of Multiple Quantum NMR Coherence in Two-Spin Systems

The Lindblad equation for dissipative open systems is applied for an investigation of relaxation of multiple-quantum (MQ) NMR coherences in two-spin systems. We choose two examples of two-spin systems. One of them is the zigzag proton chain in a single crystal of hambergite in such an orientation that one of the two intra-chain dipolar coupling constants becomes zero. Then, the chain consists of well-isolated pairs of spins, with the spins of each pair coupled by the dipole–dipole interaction. The second example of a two-spin system is a single crystal of gypsum in which protons belong to water molecules. The MQ NMR dynamics with relaxation was investigated for different preparation times of the MQ NMR experiment.
