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.
