Radiation Chemistry of Cyclohexane: V. Dilute Solutions of Benzene in Cyclohexane

In a mixture of cyclohexane and benzene exposed to ionizing radiation, the yields of products derived from cyclohexane are much less than would be expected if the decomposition were proportional to the mole fraction of cyclohexane. This result, one of the most striking in radiation chemistry, was first observed in the yields of hydrogen by Schoepfle and Fellows (1). From a study of all the gaseous products Manion and Burton (2) came to the conclusion that benzene protects cyclohexane by an energy transfer mechanism. Later workers (8-6) have placed other interpretations on these and similar results. These interpretations will be discussed later.
