EPR STUDY OF CU2-CRYSTAL( ION DOPED IN POTASSIUM OXALATE MONOPERHYDRATE SINGLE)

The EPR study of Cu2+ doped potassium oxalate monoperhydrate is carrie d out at room temperature. Two magnetically inequivalent interstitial sites are found embedded in orthorhombic crystal fields. The ground st ate wave functions are constructed. The obtained results are compared with that of isotypic crystal Cu2+ doped potassium oxalate monohydrate to explore the difference arising due to the presence of H2O2 in the former and H2O in the latter crystal. The spin-Hamiltonian parameters (g- and A-values) covalency parameter (alpha'(2)), the mixing coeffici ents (alpha,beta) and Fermi contact term (k) are calculated for both t he complexes.
