Analytical expressions for the central k (0) and noncentral k (1) force constants of two-dimensional (graphene, silicene) and three-dimensional (diamond, silicon) structures have been obtained within the previously proposed model of the binding energy of carbon atoms in graphene. The Kleinman internal displacement parameter of the two-dimensional structure has been determined. It has been shown that the ratio k (0)/k (1) depends only on the dimension of the structure.
