Near equilibrium potential energy and dipole moment functions have been calculated for the electronic ground state of the XeH+ ion from highly correlated SCEP/CEPA electronic wavefunctions. The following spectroscopic constants for 132XeH+ are obtained: Re= 1.611 ± 0.005 Å, ωe = 2313 ± 50cm-1, ωexe = 41 ± 5cm-1 and D0(Xe+ + H) = 3.90 ± 0.1 eV.
Infrared transition dipole matrix elements and probability coefficients for 132XeH+ and 132XeD+ are given. The electric dipole moment functions of the protonated rare gas atoms HeH+ to XeH+ are discussed.
