摘要: EPR studies of vanadyl doped ZnSO4⋅7H2O are reported. Vanadyl is found to have fixed orientations in the lattice and there two magnetically inequivalent complexes lattice. The angular variation spectra studied crystallographic ab, bc, ac planes. principal values g A direction cosines which axes make with found. Vanadium enters substitutionally place Zn2+ gets bonded five water molecules form a stable [VO(H2O)5]2+ complex. results obtained from polycrystalline samples Mg(NH4)2(SO4)2 ⋅6H2O, K2SO4, 3CdSO4⋅8H2O also analyzed using spin‐Hamiltonian corresponding tetragonal symmetry. In optical absorption spectrum bands observed visible region attributed d–d transitions. conjunction give ...
