E.P.R. studies of Cu2+ ion in Cd(NH4)2(SO4)2. 6H2O crystals at 300 K and 77 K showed that the impurity ion has entered the substitutional Cd2+ site. The spin hamiltonian g and A parameters and their direction cosines have been evaluated from the observed E.P.R. data. The ...
The complexity of the spectrum obtained is therefore ascribed to very strong Jahn-Teller splitting which the NH4 ++ ion exhibits in the final 2 T 2 state.\nE.SektionGilbergSektionInformaworldMolecular Physics

The removal of NH4+ on protonated layered perovskite oxide HCa2Nb3O10路1.5H2O from an aqueous solution at room temperature using a batch method was investigated. The protons situated between the layers of the material are exchangeable with cations in solution. Distribution coefficient values, Kd (...
