  The influence of pressure on the structural and elastic properties of ScM (M
= Rh, Cu, Ag, Hg) compounds has been performed by using ab initio approach
pseudopotential plane- wave method based on the density functional theory
within the generalized gradient approximation (GGA). The optical properties
have been investigated under zero pressure. It is found that the optimized
lattice parameters for all metals are in good agreement with the experimental
data and other available theoretical values.
