Theoretical considerations are made on the mechanism of the admixture between the 3 T 1u and 3 A 1u states of Tl + ‐type ions, which is realized for Au − ions in alkali halides and Pb 2+ , Bi 3+ ions in alkali‐earth chalcogenides. It is shown that the ordinary electric electron‐phonon interaction has no effect on the admixture between both the states. A new model containing the magnetic interaction with the localized τ 1g vibrational mode is proposed in order to explain this admixture by the use of the two‐electron wave functions.
