Abstract The anisotropic spectra of edge absorption, photoconductivity, emission, and reflectivity of the tetragonal ZnP 2 and CdP 2 crystals have been experimentally investigated in the range 1 to 12.5 eV. The selection rules for interband transitions, the points of zero slope, and the dispersion relations at general points of the Brillouin zone have been derived by group‐theoretical methods. From an analysis of the experimental and theoretical data conceivable energy band models of the tetragonal ZnP 2 and CdP 2 crystals are proposed.
