The Phillips — van Vechten dielectric theory for binary tetrahedral compounds and Levine's extension of this theory to multibond crystals is used to evaluate the bond ionicities in the A I B III C 2 VIchalcopyrite compounds with A I = Cu, Ag from spectroscopic data. In deriving the ionicity of the A I —C VI bond the influence of the noble metal d electrons it taken into account. The results obtained are compared with previous estimations.
