Crossed laser and molecular beams were used to obtain the recoilenergy distribution of fragments in the study of multiphoton dissociation of SF 6. An average dissociation lifetime of-100 nsec was estimated from the laser pulse width dependence of the dissociation product. The results are in good agreement with the theoretical prediction of the RRKM model for unimolecular dissociation assuming an average excitation of-16 kcal per molecule beyond the dissociation threshold and complete energy randomization in the excited molecule before dissociation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
