Abstract

Excitation spectra of CdNe and CdAr van der Waals molecules were studied in freejet expansion molecular beams crossed with a beam of exciting radiation from a pulsed dye laser. The molecules were produced as Cd atoms seeded in Ne or Ar were expanded through a nozzle and the excitation spectra were recorded by scanning the second-harmonic output of the dye laser in the immediate vicinity of the Cd(51P1 _5lS)atomic transition, in the range 2288-2290.5A for CdNe and 2288-2305.5A for CdAr. Analyses of the vibrational structures of the spectra yielded the molecular constants we ' e X and De for the D 1 states of CdNe and CdAr. Computer-modelling ofthe spectrabased on calculations ofFranckCondon factors utilizing the Morse potential produced the equilibrium internuclear separations.
