A simple auxiliary model is presented that enables extracting general features of the EFG tensor distribution in icosahedral qusicrystals directly from the orientation dependence of the quadrupole-perturbed NMR spectrum. The only assumption of the model is a macroscopic icosahedral symmetry of the sample under study. It is shown that the model serves as a good filter since on the basis of the measured NMR spectrum orientation-dependence it can directly differentiate between qualitatively different icosahedral distributions of the EFG tensor orientations
