The molecular parameters of ArH＋ have been calculated with different quantum chemistry methods and basis sets.Based on the data from QCISD/Aug cc pVTZ ab initio calculation for different configurations of ArH＋ and the experimental data,an accurate potential curve for ArH＋ has been constructed.The molecular properties,such as dissociation energy,equilibrium bond length,and vibrational energy levels,can be accurately reproduced.
