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.

6) spin lattice relaxation time
自旋-晶格驰豫时间
补充资料：自旋-晶格弛豫时间
自旋-晶格弛豫时间
磁共振成像术语。磁化矢量从零恢复到其最大值的63%时所需的时间。多数的液体不易发生T1弛豫，所以T1很长。
