We trace the transformation of I = 3/2 131-Xe nuclear spin resonances from the pure nuclear quadrupole regime to the quadrupole-perturbed Zeeman regime. We achieve large nuclear quadrupole shifts by using a 1mm3 cubic cell with walls of different materials. When the magnetic and quadrupolar interactions are of comparable size, perturbation theory does not work well to calculate the transition energies, and in the general case when the axes of the electric field gradient and the magnetic field are not collinear, there is not a convenient quantization axis for describing the system. Rather than use perturbation theory, we compare our data to theoretical calculations using a Liouvillian approach and find excellent agreement.
