The potential energy for the 30 lowest molecular states 2S+1 (+) of the RbCs molecule has been calculated over a wide range of internuclear distances, using an ab initio method based on non-empirical pseudopotentials, parametrized l-dependent polarization potentials and full valence CI calculations. Molecular spectroscopic constants have been derived for the bound states. An accurate description of the few experimentally known states is obtained. Extensive tables of energy values versus internuclear distances are available at the following address: http://lasim.univ-lyon1.fr/allouche/rbcs.htm.

The potential energy has been calculated for the 49 lowest molecular states Ω( + /-) of the molecule RbCs within the 5-23 a0 range of internuclear distances R. Spin-orbit interactions are taken into account through a semi-empirical spin-orbit pseudo-potential added to the electrostatic Hamiltonian. Molecular spectroscopic constants have been derived for bound states in the vicinity of their (inner) well. To the best of our knowledge, the vast majority of the results presented here are the first for this molecule.
