The theory of single passage nuclear magnetic resonance on oriented nuclei with small electric quadrupole interactions

Abstract

The theory relevant to the observation of nuclear magnetic resonance of dilute impurities in solids, by the change in the gamma- and beta-ray emission distributions from oriented nuclei, is discussed for the situation where an electric quadrupole interaction produces a splitting of the nuclear magnetic resonance line comparable with the interaction energy with the applied RF field. The major deviations from conventional adiabatic fast passage expected for a single sweep of the RF frequency through the resonance condition are shown to be well reproduced by recent experimental results, indicating the validity of the theoretical model discussed.
