Paper Abstract

The supersonic beam method combined with techniques of laser spectroscopy has been used for determination of the excited-state interatomic potentials of the heteronuclear CdRg (Rg=rare gas: Ar and Kr) and homonuclear Zn2 van der Waals (vdW) molecules. In the experiments, the CdRg or Zn2 molecules were produced in a free-jet supersonic beam. The dimers were excited with a dye-laser beam in a vacuum chamber and the resulting total fluorescence emitted perpendicularly to the direction of the molecular and laser beams was recorded with a photomultiplier. Unstructured bound-free profiles in the CdRg that were first-time detected in the excitation at D10+(1Σ+)←X10+(1Σ+) transition as well as well-resolved bound-bound vibrational transitions in the Zn2 detected at the 30+u(3Πu)←X10+g(1Σ+g transition are presented. Analysis of the bound-free excitation spectra yielded information on the repulsive wall of the D10+-state potential in CdAr and CdKr, whereas analysis of the bound-bound excitation spectra lead to the determination of the 30+u-state potential parameters in Zn2.
