Abstract
IR photo-dissociation spectra of SF6 clusters have been studied. A He-seeded molecular beam has been attenuated by crossing it with a line tunable cw CO2 laser of moderate power. - In the electron bombardment beam ionizer (Eel=100eV) small neutral clusters are found to fragment predominantly to the main monomer mass (SF5+). - Predissociation spectra have been calculated for clusters containing up to six SF6-molecules invoking the dipole-dipole resonance force to lift the degeneracy of the molecule - excited molecule interaction. On the basis of these spectra, dimer and trimer concentrations have been determined quantitatively, for different molecular beam conditions.
