论文摘要
Redfield的主方程是针对具有旋转$ i = 7/2 $的核系统的分析求解的。每个密度矩阵元件的溶液使用不可约张量操作员基础计算。在夜间溶剂阶段和室温下，在lyotropic液晶样品中的Caesium-pentadecafluoroocittanoate分子的$^{133} $ CS核用作实验设置。监测了$^{133} $ CS核信号的实验纵向和横向磁化动力学，并通过数值程序，理论方法产生有价值的数学表达式，其精度最高。引入的方法可以扩展，而没有重大困难到其他核物种。
Redfield's master equation is solved analytically for a nuclear system with spin $I=7/2$. The solutions of each density matrix element are computed using the irreducible tensor operator basis. The $^{133}$Cs nuclei of the caesium-pentadecafluorooctanoate molecule in a lyotropic liquid crystal sample at the nematic phase and at room temperature was used as an experimental setup. Experimental longitudinal and transverse magnetization dynamics of the $^{133}$Cs nuclei signal were monitored and by numerical procedures the theoretical approach generates valuable mathematical expressions with the highest accuracy. The methodology introduced could be extended without major difficulties to other nuclei species.
