Kinetics and Product Branching Ratio Study of the CH₃O₂ Self-Reaction in the Highly Instrumented Reactor for Atmospheric Chemistry.

ABSTRACT: The fluorescence assay by gas expansion (FAGE) method for the measurement of the methyl peroxy radical (CH₃O₂) using the conversion of CH₃O₂ into methoxy radicals (CH₃O) by excess NO, followed by the detection of CH₃O, has been used to study the kinetics of the self-reaction of CH₃O₂. Fourier transform infrared (FTIR) spectroscopy has been employed to determine the products methanol and formaldehyde of the self-reaction. The kinetics and product studies were performed in the Highly Instrumented Reactor for Atmospheric Chemistry (HIRAC) in the temperature range 268-344 K at 1000 mbar of air. The product measurements were used to determine the branching ratio of the reaction channel forming methoxy radica
