The spectra of solvated electrons (e;) in n-hexane, cyclohexane, methylcyclohexane and isopeatane at room temperature have been obtained. Electron-cation recombination reactions are second order and have rate constants 1-20 x 1014 M-1 s-1 at 20°C. The rate constants for the reaction of e; with pyrene and carbon tetrachloride in n-hexane are 1.0 x 10l2 M-' s-' and the latter reaction has an activation energy of 5+ 1 kcal mol-'. The relationship of these observations to mobilities of electrons in hydrocarbons measured by conductivity is discussed.
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.
