Abstract
By adopting the uniform high order perturbation formulas of Knight shifts and g factors for 3d9 ions in orthorhombically and tetragonally elongated octahedra, the experimental results of these parameters for Cu(1) sites in YBa2Cu3O7, YBa2Cu3O7âÏ and YBa2Cu4O8 and Cu(2) site in YBa2Cu3O7âÏ are systematically investigated. The calculated Knight shifts (and g factors for Cu(2) site) agree well with the observed values. The anisotropies of the g factors and Knight shifts are attributed to the local orthorhombic and tetragonal elongations of the Cu2+ sites. The present studies would be helpful to attain a more complete spectroscopic understanding for g factors and Knight shifts.
