The electronic band structure of InS is calculated for the first time using the empirical pseudopotential method. A group‐theoretical study of the symmetry properties of InS is included. The resulting energy bands are then used to calculate the imaginary part of the dielectric function for each polarization along the principal axes of InS. The total and partial electronic densities are mapped on the (110) plane. Comparisons are made with previous experimental studies.
