A calculation of the coefficient Cₖ of the terms linear in k in the Γ₈ valence bands of several III-V semiconductors is presented. On the basis of the systematics of these results it is concluded that these terms arise from coupling by the linear momentum and the spin-orbit operators to the uppermost d levels of the core. A simple analytic expression to calculate Cₖ for all III-V, II-VI, and I-VII compounds with zinc-blende structure is proposed. The results are in good agreement with the few experimental data available.
