Abstract
The electron-pulse radiation-induced conductivity of aromatic hydrocarbon solutions in cyclohexane and its dependence on the concentration and time are investigated. A current I e due to the electron conductivity is revealed at a concentration of solute [ A] less than 10 −5 mol dm −3. The dependence of I e on [ A] and known values of electron and ion mobilities in cyclohexane lead to rate constants for electron capture by A of (2,1 ± 0,4) × 10 12 and (2,3 ± 0,4) × 10 12 dm 3 mol −1 s −1 for pyrene and diphenyl respectively. The electron and positive ion recombination rate constants are shown to be close to theoretical values for diffusion-controlled recombination.
