The spin Hamiltonian parameters (SHPs) (thegfactorsgiand the hyperfine structure constantsAi,i=x, y, z) and the local structure of the substitutional Cu2+center in rutile (TiO2) are theoretically studied from the perturbation formulas of these parameters for a 3d9ion in rhombically elongated distorted octahedra. The related molecular orbital coefficients are quantitatively determined from the cluster approach in a uniform way, and the required crystal-field parameters are estimated from the superposition model which enables correlation of the crystal-field parameters and hence the studied SHPs with the local structure of the Cu2+center. Based on the studies, the Cu–O bond lengths parallel and perpendicular to theC2-axis are found to beR||’≈ 2.030 Å andR⊥’≈ 1.924 Å, respectively, with the planar bond angleθ≈ 87.21°. The calculated SHPs are in agreement with the experimental data and the results are discussed.
