Abstract

The properties of ozonide and hydroperoxy radicals were studied in the flash photolysis of H₂O₂. Evidence for the reaction (Formula Presented.) was found. The spectrum of O⁻₂ is given with λ_max = 240 nm and ϵ₃₄₀ = 1900 ± 100 M⁻¹ cm⁻¹. No evidence was found for the existence of H₂O⁺₂. The recombination kinetics of the hydroperoxy radical are discussed. It was shown that O⁻₃ has no absorption in the UV. The reaction of O⁻₃ with H₂O₂ was shown to proceed via dissociation of O⁻₃ into O⁻, and the product of the reaction was identified as O⁻₂. No ozone is found in the decay of O⁻₃.
