摘要：

The response of a spin system to a long (in comparison to spin-spin relaxation time T-2) radiofrequency pulse has been studied. We observed that the magnetization after the long pulse does not fall to zero at time t much greater than T-2 for both on-resonance and off-resonance conditions. The dependencies of the magnetization on frequency offset, linewidth and radiofrequency power are investigated, both theoretically and experimentally. The question of the effective field direction is also discussed. (C) 1998 Elsevier Science B.V. All rights reserved.
