Using the μ k α model of Ni 2+ −6X − clusters the true distances between impurity Ni 2+ cation and halogen anion in alkali halide lattices are estimated from the optical spectral data. The results suggest that the true impurity cation‐ligand anion distances are close to the sum of ionic radii of the impurity cation and anion but not the cation‐anion distance of the perfect lattices in the case that the ionic radius of host cation is larger than that of impurity cation.
