The coinage metal polonide molecules MPo(X2∏), (M=Cu, Ag, Au) have been studied using standard small-core relativistic pseudopotentials. The ground electronic states and corresponding reasonable dissociation limits are deduced with the group theory and the principle of atomic and molecule reaction statics. The equilibrium geometries and vibrational frequencies are calculated at the several theoretical levels of electron correlation methods. The total space analytical potential functions for species are constructed by fitting the energy curves as Murrell-Sorbie function, and spectroscopic data and force constants are derived from it. This investigation constitutes the first theoretical study of MPo,(M=Cu,Ag,Au) systems.
