Abstract (summary) In the present paper we focused our attention on problems of property variable of materials by interstitial impurity-induced perturbation of regular structure. This problem may be solve by NMR study of quadrupolar nuclear, that is probe of electronic environment of guest atom embedded in a host lattice. The study of evolution of coherences of quadrupolar nuclear with spin S = 3/2 in the presence anisotropy chemical shift is shown that interference terms between time dependent quadrupolar interaction and anisotropy chemical shift are induce dynamic shifts of satellites and difference broadening line of its. The extraction of Q-CSA interference terms from NMR experimental data give us not only tensor parameters but the information about a location of tensor principal axes.
