Item Observations on Solvated Electrons in Aliphatic Hydrocarbons at Room Temperature by Pulse Radiolysis(Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1973, 69 (4), 1973) Baxendale, J. H.; Bell, C.; Wardman, P.The spectra of solvated electrons (e–s) in n-hexane, cyclohexane, methylcyclohexane and isopentane at room temperature have been obtained. Electron-cation recombination reactions are second order and have rate constants 1–20 × 1014 M–1 s–1 at 20°C. The rate constants for the reaction of e–s with pyrene and carbon tetrachloride in n-hexane are 1.0 × 1012 M–1 s–1 and the latter reaction has an activation energy of 5 ± 1 kcal mol–1. The relationship of these observations to mobilities of electrons in hydrocarbons measured by conductivity is discussed.Item Yield of Excited Singlet and Triplet States in the Pulse Radiolysis of Toluene(Journal of the Chemical Society : Faraday Transaction - I. The Chemical Society, London. 1973, 69 (4), 1973) Baxendale, J. H.; Rasburn, E. J.The 100 eV yield of the excited singlet state of toluene following a pulse of 10 MeV electrons is found to be 1.35, and the rate constant for its reaction with naphthalene to give the excited naphthalene singlet is 5.4 × 1010 M–1 s–1. The corresponding yield of the triplet state of toluene is 2.8 and assuming it reacts with naphthalene at a normal diffusion controlled rate, its half life is calculated to be 17 ns.
