摘要
本文研究了双极化子体系在随机行走模型下的核磁弛豫,给出了Heitler-London三重态双极化子(HLTB)的自旋晶格和自旋自旋弛豫时间与Larmor频率的关系式。从这些关系式中得知用核磁共振方法无法检测到双极化子体系中非四极核的信号。
In this paper, the nuclear magnetic relaxation in bipolaronic system is investigated theoretically under the random walking model. The relationship between two relaxation times and the Larmor fequency has been given for Heitler—London triple bipolarons (HLTB). The re- sults is that the nuclear magetic signal fo non—quadrapole nuclei in biplaronic system can not be detected.
