| Abstract: | The EPR study of the Cu2+-doped tris-sarcosine calcium chloride (TSCC) at room temperature is reported. Two magnetically inequivalent sites for Cu2+ were observed. The rhombic spin Hamiltonian parameters are determined by fitting the EPR spectra for two centres: Cu2+(I) g1 = 2.0276, g2 = 2.0517, g3 = 2.4019, A1 = 82, A2 = 128, A3 = 152 [G] and Cu2+(II) g1 = 2.0231, g2 = 2.0368, g3 = 2.5294, A1 = 76, A2 = 92, A3 = 156 [G]. The ground state wave function is also determined. The g-anisotropy is evaluated and compared with the experimental value. Further, the optical study of the crystal at room temperature is carried out and the nature of bonding in the complex is discussed. |
