The photo-oxidation of azoethane has been studied by molecular modulation spectroscopy in order to determine the overall rate constant for the second-order removal of ethylperoxy radicals between 303 and 457 K. The principal molecular products of the reaction between 302 and 373 K are acetaldehyde, ethanol and ethyl hydroperoxide. From the reaction rate data and analytical results, the following results
