Abstract
An experimental study of the properties of one form of the three-state reflection-symmetry cycle is presented. The cycle and its compensated form are used to measure the chemical shielding tensor of in polytetrafluoroethylene [] and in powdered zinc phosphide ( ). The effect of phase errors is discussed and the principle of phase compensation is demonstrated in a phase-alternated sequence. Amplitude-modulation effects of phase errors are also discussed.
