Abstract
THE hydrated electron, e−aq, and the OH radical are the principal products of the radiation induced decomposition of liquid water; with gamma rays the 100 eV yields1 of these reactive intermediates are closely approximated by the values Ge−aq ≃ GOH ≃ 2.6. While certain classes of organic compounds are known to react quantitatively with both e−aq and OH in oxygen-free solution, the observed yield for net destruction of such solutes may be quite low compared with the G value for water decomposition. In interpreting the radiation chemistry of such systems the concept of a reconstitution or back-reaction must be invoked.
