EPR of Tl2+ ions in K2SO4, Rb2SO4, Cs2SO4 crystals have been studied. Noncentrality of Tl2+ (II) ions was observed. Activation energy values of Tl(II) complexes motion were obtained. Anomalous temperature dependence of EPR line position and appearance of new EPR lines in Rb2SO4, Cs2SO4 crystals were observed.
