A magnetic resonance method is applied to the investigation of a number of isostructural diamagnetic compounds ABO{sub 3} (A = Sc, In, and Ga) with small additions of Cr{sup 3+} ions (S = 3/2) sufficient to observe single-ion and pair spectra. It is shown that the resonance spectra for isolated Cr{sup 3+} ions can be described to a good accuracy by the ordinary axial spin Hamiltonian for 3d ions in octahedral oxygen environment. The parameters of the spin Hamiltonian are determined for single Cr{sup 3+} ion and Cr{sup 3+}–Cr{sup 3+} pair. Lattice distorsions of the parent ABO{sub 3} crystals caused by the Cr{sup 3+} impurities is discussed.
