摘要: 14N核四极共振自旋系统的自旋-晶格弛豫是一种双指数弛豫。本文介绍了14N核四极共振自旋系统的自旋-晶格弛豫时间的3种测量方法,利用可变多面体方法对实验数据进行拟合,获得了14N核四极共振自旋系统的自旋-晶格弛豫时间T1s和T11,对有关文献中关于核四极共振弛豫时间的测量的3个观点提出了质疑。

Abstract: The spin-lattice relaxation for a 14N NQR spin system is a dual exponential relaxation. Three measurement methods of spin-lattice relaxation times for a 14N NQR spin system are presented in this paper,the spin-lattice relaxation times T1s and T11 have been obtained by simulating experimental data with N-SIMPLEX method.Questions about the measurements of relaxation time for an NQR spin system in some concerned references have been put forward.
