Theoretical determination of the electronic structure of KH+

Potential energy curves and dipole moments have been determined over a large range of internuclear distances, for all molecular states dissociating up to the asymptote K(4d) + H+ (i.e. for 22 2Λ(+) electronic states). Calculations have been performed through a model potential type method. Spectroscopic constants of the bound states are presented and characteristics of the humps are also reported. Both results are compared with available data.
