  Multichannel dispersed emission spectra recorded upon a selective excitation
of Rydberg electronic energy states in the ZnAr and CdAr van der Waals (vdW)
complexes are analysed as a proof-of-concept of the future experimental
approach. Simulations of the emission spectra are based on ab-initio calculated
interatomic potentials and transition dipole moments (TDMs). Experimental
set-up that is under construction along with the experimental procedure are
discussed.
