摘要：
The electron paramagnetic resonance study of Cu2+-doped bis(l-asparaginato)Mg(II) is performed at room temperature. Two magnetically non-equivalent sites for Cu2+ are observed. The spin-Hamiltonian parameters evaluated by fitting spectra to the crystalline field of rhombic symmetry are as follows: g (x) = 2.0420 +/- A 0.0002, g (y) = 2.0808 +/- A 0.0002, g (z) = 2.3600 +/- A 0.0002, A (x) = (99 +/- A 2) x 10(-4) cm(-1), A (y) = (108 +/- A 2) x 10(-4) cm(-1), A (z) = (140 +/- A 2) x 10(-4) cm(-1). The ground state wave function of Cu2+ is also determined. The g-anisotropy is estimated and compared with the experimental value. Further, with the help of optical study the nature of bonding of a metal ion with different ligands in the complex is discussed.
