The paramagnetic resonance spectrum of Ti3+ ions in potassium alum (KAl(SO4)2∙12H2O) single crystals has been studied in the {100} planes at 4.2 K with an X band microwave spectrometer. The spectrum is an analogue of that reported by Dionne for Ti3+ ions in rubidium alum (RbAl(SO4)2∙12H2O) and by MacKinnon and Dionne for Ti3+ ions in the thallium alum (TlAl(SO4)2∙12H2O). The spectrum was explained with a model of 12 magnetic complexes, the complexes being related to each other through the symmetry elements of the [Formula: see text] point group of the alum lattice. The three g factors for the spin Hamiltonian with S = 1/2 were found to be 1.979, 1.898, and 1.828, with an accuracy of ±0.005.
