The ESR study of the Cu2+ doped zinc glutamate dihydrate is carried out at room temperature. Two magnetically nonequivalent sites for Cu2+ are observed. The spin Hamiltonian parameters are determined with the fitting of spectra to rhombic symmetry crystalline field. The parameters are as follows: Cu2+(I): gx = 2.0170 ± 0.0002, gy = 2.0768 ± 0.0002, gz = 2.2334 ± 0.0002, Ax = (74 ± 2) × 10−4, Ay = (99 ± 2) × 10−4, Az = (134 ± 2) × 10−4 cm−1and Cu2+(II): gx = 2.0180 ± 0.0002, gy = 2.0550 ± 0.0002, gz = 2.1633 ± 0.0002, Ax = (100 ± 2) × 10−4, Ay = (100 ± 2) × 10−4, Az = (115 ± 2) × 10−4 cm−1. The ground state wave function is also determined. The g-anisotropy is evaluated and compared with the experimental value. Using the data of optical absorption study undertaken at room temperature the nature of bonding in the complex is also discussed.
