The extended Solomon equations are used to describe the 13 C spin lattice relaxation with the 1H RF field irradiation It is shown that the 13 C spin lattice relaxation with the 1H RF field irradiation is generally a triple exponential course, which can be reduced to a single exponential course in the absence of the 1H initial magnetization and with strong enough RF field irradiation.

补充资料：自旋-晶格弛豫
自旋-晶格弛豫
磁共振成像术语。又称纵向弛豫(longitudinal relaxation)或T1弛豫。指平行于外磁场B0方向的磁化矢量的指数性恢复的过程。磁共振成像时，对置于外磁场B0中的自旋系统施加射频脉冲，则自旋系统被激励，其净磁化矢量指向偏转，不再与外磁场B0方向平行(如与B0垂直)。射频脉冲终止后，被激励的质子与周围环境(晶格)之间发生能量交换，把能量传递给周围的晶格，同时其净磁化矢量指向逐渐恢复与外磁场方向平行。该过程在自旋与晶格之间有能量交换，故自旋-晶格弛豫又称热弛豫。自旋-晶格弛豫与外磁场场强有关。
