By using of NMR method and computer simulation of NMR spectra the
intrinsic defects of congruent LiNbO3 crystals have been investigated.
The method of defect structure studying based onto the angular dependens
of the ferst moment of central line of NMR spectra analysis and based
onto the comparing of computer simulation data and experimental results
are proposed. It is proposed the new method of EFG calculation into the
crystals with ionic-covalenty bonds, as the two methods of the
quadrupole nuclei NMR spectra simulations, based on the calculation of
EFG tenzor. It has been shown that the main type of intrinsic defects
into congruent LiNbO3 are the complexes (NbLi + 3VLi) and isolated Vli
at ratio 1:1.
