Central shifts of the Mössbauer emission spectra on impurity atoms 67Cu(67Zn) in the crystal lattices of lithium and rubidium halides are determined. Relativistic Doppler shifts of the spectra are calculated and, as a result, isomeric shifts are obtained. The are compared with the nature of the chemical bond of zinc atoms with halogen atoms in the crystals under study. The values of the quadrupole interaction constants for zinc impurity centers in lithium and rubidium halide are consistent with the values obtained in the ionic model calculations.
