ENDOR investigations show that in nearly stoichiometric LiNb03 Mn 2+ substitutes for Li with a Li vacancy in the first Li shell for most centres. In heavily Mg codoped LiNbO3 the Cr3+dopant, characterized by a new isotropic ESR signal, is shown to substitute for Nb. Information on local disorder is obtained.
