A magnetic resonance method is applied to the investigation of a number of isostructural diamagnetic compounds ABO{sub 3} (A = Sc, Lu, In) with small additions of Cr{sup 3+} ions (S = 3/2) sufficient to observe single-ion 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. It is established that Cr{sup 3+} ions in these crystals are characterized by easy-axis-type anisotropy.
