N2 - The effective bond charge qeff, as determined from experimental values of the third-order optical susceptibility in alkali halides, is analyzed. The correlations of qeff with the ratio of the cation to anion radius, lattice constant and Szigeti effective charge are taken into account. The relationships between qeff and other parameters describing the ionicity show that the magnitude of qeff can be considered as one more parameter related to the ionicity of the crystals.
