- Abstract
It was found by flash photolysis that the overall kinetics of diphenylcarbonyl oxide disappearance in acetonitrile, benzene, and n-hexane has both a bimolecular and a monomolecular component. The monomolecular route is the isomerization of diphenylcarbonyl oxide into dioxirane. The activation parameters of this process were measured. The activation energy of the biomolecular decay of diphenylcarbonyl oxide is slightly positive for acetonitrile, is close to zero for benzene, and is negative for n-hexane. This dependence of the activation energy on the nature of the solvent is due to the fact that the reaction includes the equilibrium formation of an intermediate species.
