| Summary: | The theory for the combined effects of both a quadrupolar interaction and a Knight shift has been examined for the case of non-axial symmetry. A detailed derivation is given, correct to second order in perturbation theory, for the case where the quadrupole interaction is significantly smaller than the Zeeman interaction. These results have been applied to the study of the Al' nuclear magnetic resonance spectrum of a single crystal of UNi2A/3, measured using a steady state technique. A value for the asymmetry of the electric field gradient has also been determined for this material. In addition, the temperature dependence of the Knight shift was observed over the range of 6 to 300K.No significant temperature dependence was found over this range. === Science, Faculty of === Physics and Astronomy, Department of === Graduate
