Abstract
The effective bond charge q(eff), as determined from experimental values of the third-order optical susceptibility in alkali halides, is analyzed. The correlations of q(eff) with the ratio of the cation to anion radius, latti ce constant and Szigeti effective charge are taken into account. The relati onships between q(eff) and other parameters describing the ionicity show th at the magnitude of q(eff) can be considered as one more parameter related to the ionicity of the crystals.
