The potential curves of the electronic states of Ag-2 molecules

The potential energy curves were determined for the ground (X(1)Z(g)(+)) an d excited (A(1)Sigma(u)(+), B(1)Pi(u), C(1)Pi(u), D(1)Sigma(u)(+), and E(1) Pi(u)) electronic states of silver dimer. Each potential curve was approxim ated by three functions. The lower parts of the potential curves were appro ximated by perturbed Morse oscillator functions, and the middle parts, by R ydberg-Klein-Ries functions. The potential curve regions corresponding to l arge internuclear distances were described by van der Waals functions. The reliability of the potential curves was verified by comparing the experimen tal molecular constants with those obtained by solving the radial wave equa tion.
