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.
