The Mössbauer spectroscopy with 119 Sn isotope shows that tin atoms in Pb 1‐x Sn x S and Pb 1‐x Sn x Se solid solutions are electrically active donor centers with charge states determined by acceptor impurities occuring in the solid solutions. The neutral state and the ionized one of the tin donor centers are identified as Sn 2+ and Sn 4+ , respectively. A two‐electron exchange between the neutral and ionized tin centers is observed for the Pb 1‐x Sn x Se solid solutions doped with sodium and thallium acceptor impurities.
