The superposition model has been used to investigate the substitution of Mn2+ in ammonium oxalate monohydrate. The zero field splitting parameters D and E calculated by the superposition model are compared with the experimental values Dexp and Eexp, respectively, for Mn2+ obtained by electron paramagnetic resonance. Both the zero field splitting parameters D and E calculated theoretically are in good agreement with the experimental values Dexp and Eexp. The result indicates that the Mn2+ ion substitutes for the NH4+ ion in ammonium oxalate monohydrate. |
