• Electron paramagnetic resonance of KAI(SO.).- l2H.O and NH.Al(SO.).- 12H.Odoped with Tl" was investigated in the interval of temperature 65 K-160 K. Thechanges in the EPR spectra of the Tl" ion in both doped crystals are discussed basedon the influence of a reorientational model for sulfate groups. A model to explain con-flicting data reported in the literature and concerned with the presence of a phase Iransition in non-polarizable cz-alums is suggested. Also, the changes of the EPRparameters near the phase transition in polarizable cx- and /7-alums are discussed here.
