Popis: The ArKr+ emission from a jet discharge has been recorded at high resolution from 6170 to 6460 A. The isotope structure due to the natural abundances of 84Kr and 86Kr establishes the vibrational analysis of the system and leads to extrapolated upper and lower state dissociation limits that are in fair agreement with photoionization data from other sources. The rotational analysis confirms the assignments of the bands to the charge transfer transition from the highest to the lowest Ω = 12 state of the ground state configurations Ar+ + Kr and Ar + Kr+, respectively. The rotational numbering of the lines follows from a careful search for common combination differences. However, the case “c” structure of the bands and the observation of only four out of a possible six branches prevent an unambiguous evaluation of the internuclear distances. The results are reviewed in the context of published high-resolution data for other rare gas dimer ions.
