It is postulated that Ti3+ exists in 12 differently oriented, but otherwise equivalent, magnetic complexes in CsTi(SO4)2∙12H2O and titanium-doped CsAl(SO4)2∙12H2O alums. This explanation appears to clear up the discrepancy between the theory and the experimental g values found by ESR measurements. The analysis indicates that the titanium ion in alums exhibits a particular class behavior and this is true whether the titanium exists in dilute or concentrated form.
