Abstract  

Gamma-irradiated at 77 K 1,4-dioxane and morpholine have been studied by ESR-spectroscopy. C-O bond dissociation is the main process in the γ-radiolysis of 1,4-dioxane and a significant contribution of −CH−CH=O radicals to the experimental spectrum is observed. Both H-atom abstraction and the cleavage of the ring seems to occur at low temperature γ-radiolysis of morpholine. The paths of formation of intermediates in cyclic ethers γ-irradiated at 77 K are discussed.
