摘要	When the monovalent md(9) ions Ni+ (3d(9)), Pd+ (4d(9)) and Pt+ (5d(9)) substitute for the Ag+ ions in AgCl crystal, the cubic chlorine octahedron surrounding Ag in the host AgCl crystal distorts into the tetragonally elongated octahedron in the md9 impurity center owing to the Jahn-Teller effect. The spin-Hamiltonian parameters (g factors g(parallel to) g(perpendicular to), and hyperfine structure constants A(parallel to), A(perpendicular to)) of the tetragonal md(9) centers in AgCl are calculated from the high-order perturbation formulas based on the cluster approach, in which the admixture between d orbitals of d(n) ion and p orbitals of ligand ion via covalence effect are taken into account. From the calculations, the spin-Hamiltonian parameters of these tetragonal md(9) centers in AgCl are explained reasonably and the tetragonal distortions (characterized by the tetragonal elongation Delta R = R-parallel to - R-perpendicular to, where R-parallel to and R-perpendicular to denote the metal-ligand distances parallel with and perpendicular to the tetragonal axis) of these centers due to Jahn-Teller effect are obtained. The results are discussed. (C) 2010 Elsevier B.V. All rights reserved.
