Abstract
ALTHOUGH the fate of the secondary electron in the radiolysis of water has been discussed for many years, most workers have assumed that it returns to the parent ion in condensed saturated hydrocarbon systems and have interpreted radiolysis data in terms of excited molecules and free radicals. However, the occurrence of ion-molecule reactions in such systems has been discussed by Libby1 and Williams2, both of whom have put forward indirect evidence for such reactions3–6. The action of several solutes has been interpreted in terms of secondary electron scavenging7–9, and Freeman10 and Allen11 have shown by conductivity measurements on irradiated cyclohexane and n-hexane respectively that low yields of free electrons and hence positive ions occur. However, direct evidence for ion-molecule reactions in such systems is still lacking.
