Abstract

Inelastic x-ray scattering spectra excited at the $1 s^{- 1} π^{*}$ resonance of gas phase $O_{2}$ have been recorded with an overall energy resolution that allows for well-resolved vibrational progressions. The nuclear wave packet dynamics in the intermediate state is reflected in vibrational excitations of the electronic ground state, and by fine-tuning the excitation energy the dissociation dynamics in the predissociative $B^{'} {}^{3}Π_{g}$ final state is controlled.
