The aim of this work is to evolve a theory for obtaining anharmonic properties of alkali cyanides using long-range Coulomb and short-range Börn Mayer potentials starting from nearest-neighbour distance and hardness parameter. An attempt has been made to evaluate higher order elastic constants and related physical properties of alkali cyanides such as LiCN, NaCN, KCN and RbCN at different temperature ranges. The computed values of SOECs, TOECs and FOECs have been used to estimate the FOPDs of SOECs and TOECs, SOPDs of SOECs and partial contractions. While evaluating the properties, it is assumed that the crystal structure does not change during temperature variation. A comparison has been made the available theoretical and experimental data.
