The ion-pair satellite band located in the blue wing of the rubidium second resonance doublet line was observed in the absorption measurements of a dense rubidium vapor. The observed satellite band was identified as a long-range ion-pair state, by using the long-range potential curves based on ab initio calculations. In order to perform the semiclassical spectral simulations of the observed satellite band, the relevant long-range potential curves and corresponding molecular dipole oscillator strengths were calculated using the asymptotic method. The importance of the observed satellite band (long-range ion-pair state) is discussed in connection with the formation of ultracold molecules.
