Short-range repulsion in the D1Σ0+-state potential of the ZnRg (Rg = Ne, Ar, Kr) complexes determined from a direct free ← bound excitation at the D1Σ0+←X1Σ0+ transition

Analysis and simulation of the unstructured free ← bound profiles recorded for the first time in excitation spectra using the D1Σ0+←X1Σ0+ transition yield information on the short-range D1Σ0+-state potential of ZnNe, ZnAr and ZnKr complexes.
