Abstract

The extent of K-mixing in the dissociation of ketene on its S₀ potential energy surface has been investigated. Using a two-step photodissociation scheme for ketene and laser-induced fluorescence (LIF) to detect the CH₂ radical, photofragment excitation (PHOFEX) spectra of high energy selectivity were recorded. The ratio of the step heights shows that K is strongly mixed for K>0 and that for K=0 the extent of mixing increases with J.
