The Cage Effect

  • E. T. Denisov


Upon decomposition of a molecule in the gas phase, the decomposition products—radicals—immediately fly apart in different directions. The decomposition of a molecule in the liquid phase leads to the formation of two radicals that exist side by side for a certain time, surrounded by solvent molecules (in a cage). Since the rate constant for the interaction of two radicals is very high, some such radicals will have time to react with each other before the pair is separated by diffusion. The main principles of the cage-effect theory were formulated by Frank and Rabinowitch [266]. In the 1950’s and 1960’s, widespread experimental evidence was obtained to support this theory.
