The ignition of ethylene-oxygen mixtures highly diluted with argon was studied in a shock tube by monitoring the emission from CH<SUP>*</SUP> and C<SUB>2</SUB><SUP>*</SUP> or OH<SUP>*</SUP>. The measurements covered the temperature range of 1400–2100 K at the C<SUB>2</SUB>H<SUB>4</SUB>/O<SUB>2</SUB> ratios of 0.33–1.00. From the observation of the CH<SUP>*</SUP>, C<SUB>2</SUB><SUP>*</SUP>, and OH<SUP>*</SUP> emissions, a mechanism for the production of chemiluminescent species upon ethylene oxidation was briefly discussed, and from the observation of the induction period of the CH<SUP>*</SUP> emission, the following equation was found:<BR>logτ_CH[O_2]=-11.45+27.5×10^3/4.58T <BR>in units of s mol l<SUP>−1</SUP>, the rate-determining step being C<SUB>2</SUB>H<SUB>3</SUB>+O<SUB>2</SUB>→C<SUB>2</SUB>H<SUB>3</SUB>O+O.
