Spin-locking in one pulse NMR experiment Academic Article uri icon

abstract

  • 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.
