Relative Intensities of Zeeman Components in Nuclear Quadrupole Resonance Spectrum

Abstract

The transition probabilities for the Zeeman components in nuclear quadrupole resonance spectrum were formulated in the case of arbitrary field gradient. Interesting behaviours were revealed especially for a nucleus of half-integral spin. When a magnetic field is applied in a direction perpendicular to the principal z -axis in the case of nonaxial field gradient due to the surrounding charges, the inner pair of the Zeeman components is produced by the x -component of the rf field and the outer pair by the y -component. The dependence of the intensities on the Zeeman field is in general not symmetric with respect to the principal axes of the field gradient.
