In the analysis of crystal binding based on the interionic force model, the contributing arising from coulomb interactions, the dipole-dipole (d-d) and dipole-quadrupole(d-q) interactions and the short-range repulsive interactions of the Hellmann and Varshni-Shukla interaction potential model.The calculated values of Grûneisen parameter, , Anderson Grûneisen parameter using two different formula for each parameter and Second Grûneisen parameter are reported here for alkali chalcogenide crystals(oxides and sulphides) of NaCl-structure. The high pressure behaviour of these crystals has also been studied. The graphical natures of calculated values I.R. absorption frequency-reduced mass and calculated values Debye temperature-reduced mass are also shown. The results obtained here may add a little to the physics and chemistry of these crystals.
