摘要：
According to WBR theory and the character of homonuclear system, the relaxation equations of homonuclear system with RF irradiation are deduced by means of the three-dimensional Wigner rotation matrix. The computation formulas of transverse and longitudinal relaxation with RF radiation are proposed, and the effects of RF irradiation on relaxation are investigated. Finally, the following; conclusions are gained. (1)The RF irradiation has effect on the relaxation course in a homonuclear system to some extent. (2) The longitudinal relaxation time T-1 with RF irradiatoin is shorter than that without RF irradiation, while the transverse relaxation time T-2 with RF irradiation is longer than that without RF irradiation. (3) With the growth of RF irradiation, T-1 is reduced, while T-2 is increased.
