Abstract

The EPR spectra of Cu(II) ion in Gamma glycine single crystal recorded in X-band frequency at room temperature reveal the presence of two sites in the lattice. Spin Hamiltonian parameters, obtained from single crystal EPR spectra, recorded in three mutually orthogonal planes, exposed the presence of Cu(II) ion incorporated in interstitial site. The principal values of the g- and A-tensors indicates orthorhombic symmetry around the Cu(II) ion. The bonding parameters were evaluated and the ground state wave function of Cu(II) ion was constructed. The optical absorption spectrum shows three bands confirming the distorted octahedral symmetry around the Cu(II) ion.
