A double resonance technique designed to allow study of quadrupolar interactions in nonintegral spin systems is described using both theoretical calculations and experimental data. The interferometric technique involves indirect detection of quadrupolar-broadened satellites by observation of only the central 1/2↔-1/2 transition. Changes in the phase factor of one wavefunction in a multilevel quadrupolar split spin system are monitored by observation of the free-induction decay of the central transition, while a 360° pulse at a second (search) frequency is applied. Particular consideration is given to the accurate reproduction of an inhomogeneously broadened satellite, and several spectroscopic schemes are compared theoretically and tested experimentally using the 23Na satellites in single-crystal sodium nitrate. Emphasis was placed on the important roles of H1 broadening and coherence transfer to the double quantum states.
