Abstract

The internal interactions in spin systems depend on the magnetic field strength, since the latter perturbs the electronic wave functions. The changes in the interaction tensors are approximately proportional to the applied magnetic field. This effect is experimentally most significant for quadrupolar spin systems, since the quadrupolar interaction is usually the strongest. This field dependence of internal interactions, seldom considered before, may lead to an ambiguity in the explanation of nuclear magnetic resonance (NMR) experiments of quadrupolar spin systems.
