Abstract : Experiments involving electric-field modulation of the optical absorption and EPR spectra of off-centre Co2+ ions in SrO are reported. The field-induced changes in the optical spectra are assigned to the combined effects of Stark shifts and to the redistribution of off-centre electric dipoles amongst the 8 possible < 111 > orientations. Measurements of the reorientation rate may be fitted by a classical Arrhénius process with activation energy 0.017 eV and pre-exponential factor τ0 = 1.2 × 10-9 s.
