Abstract
The apparent reductions in the trigonal field and spin‐orbit interactions in Ti3+ ion doped in Al2O3 is explained to be due to the presence of a moderate Jahn‐Teller effect. The spin‐orbit, trigonal field, and a part of the Jahn‐Teller interaction which causes three equivalent oscillations along the three pseudo‐fourfold axes of the complex, are treated on equal footing. The effect of the tunnelling through the potential barriers between these equivalent oscillations is considered as a perturbation. The resulting ground wave functions are used to calculate the EPR g‐values. The theoretical values are compared with the experimental magnetic and spectroscopic results.Keywords
