Mechanistic Investigation of the HO+HO2 Reaction

A steady-state photolysis experiment including mass-spectrometric end-product analysis was used to conduct a mechanistic investigation of the H(18)O+HO2 reaction system.The results obtained do not support the existence of a linear adduct reaction intermediate as suggested by a proposed pressure dependennce for the title reaction: HO+HO2->H2O+O2 (k₁).An elaborate modeling analysis of the experiment best matches the observed product yields for values of k₁ in the range 1*10^-10-2*10^-10 cm³ molecule^-1 s^-1.
