Abstract
Informations on excited electronic states of the heteronuclear rare-gas dimers XeRg (Rg=Kr, Ar) available in the literature are limited to the vibrational structure of several band systems in the VUV range of the electromagnetic spectrum.% , \emph{J. Phys. B} \textbf{29}, L89 (1996). O. Zehnder, F. Merkt, \emph{Mol. Phys.} \textbf{106}, 1215 (2008). %KrXe+ O. Zehnder, F. Merkt, \emph{J. Chem. Phys.} \textbf{128}, 014306 (2008). %ArXe+ } Using a near-Fourier-transform-limited vacuum-ultraviolet laser system% , \emph{Rev. Sci. Instr.} \textbf{71}, 4023 (2000).} spectra of the C$\,\leftarrow\,$X and D$\,\leftarrow\,$X band systems of several isotopomers of XeKr and XeAr were recorded at high resolution in the wavenumber range from 77\,000\,cm$^{-1}$ to 77\,350\,cm$^{-1}$ by resonance-enhanced two-photon ionization spectroscopy. The rotational and vibrational structures of the C$\,\leftarrow\,$X and D$\,\leftarrow\,$X band systems could be fully resolved and assigned on the basis of isotopic shifts, combination differences and the ground state microwave spectra% , \emph{J. Chem. Phys.} \textbf{99}, 919 (1993).}. The orbital hyperfine structure of the C1 state could be resolved for the $^{129}$Xe$^{40}$Ar and $^{131}$Xe$^{40}$Ar isotopomers. Potential energy functions and a full set of spectroscopic parameters were derived for the ground and excited states.
