Abstract
The crystalline state properties such as cohesive energy, atomization energy, force constant, IR absorption frequency, Debye temperature, Griineisen parameter, Anderson Griineisen parameter, Moelwyn-Hughes parameter of heavy metal halide are reported here. These parameters have been obtained by using the Born-Mayer, Hellmann, Varshini-Shukla and Ali-Hasan interionic short-range repulsive interactions. Calculations are also performed for the computation of first order volume dependence of Griineisen parameter commonly known as second Griineisen parameter using expressions of higher order derivatives of interaction potential within the framework of Dugdale and MacDonald theory. The high pressure behaviour of these crystals has also been studied.
