Abstract
In pulsed nuclear magnetic resonance a random variation of the nutation angle is produced if the rf pulse initiation occurs at a random phase with respect to the rf carrier. The effect is most important at low resonance frequencies and large rf pulse amplitudes. An approximate calculation of the rms variation is presented, and a circuit is described which minimizes the variation by synchronizing the rf pulse with the rf phase.Keywords
