用推广的Ｓｏｌｏｍｏｎ方程描述了１Ｈ通道加上射频场的１３Ｃ自旋晶格弛豫．分析表明在１Ｈ射频照射下１３Ｃ自旋晶格弛豫通常是一个三指数过程，但是在一些实验条件下可以变为单指数的；数值计算给出了满足和满足的１３Ｃ自旅晶格弛豫过程的明显差别．并显示了不同射频场强度的影响．实验观测了固体Ｌ－缬氨酸的甲基１３Ｃ自旋晶格弛豫，所得结果与理论分析很好符合．
The 13C spin-lattice relaxation of the 1H channel plus the radio-frequency field is described by a generalized Solomon equation. The analysis shows that the 13C spin lattice relaxation is usually a triple exponential process under 1 H radio frequency irradiation, but it can be changed into single exponential under some experimental conditions. The numerical calculation gives 13C self-traveling lattice relaxation The obvious difference in the process. And shows the impact of different RF field strengths. The methyl 13C spin-lattice relaxation of solid L-valine was observed experimentally and the results were in good agreement with the theoretical analysis.
