A detailed investigation of the mechanism of cyanogen oxidation is presented. Recent induction time measurements of ignition in cyanogen-xygen-argon mixtures behind reflected shocks are computer modeled to obtain an agreement between the experimental and calculated values. A 15-step reaction scheme is suggested to reproduce the parameters E and pi in the experimental parametric relation: T = lO"exp(E/RT)IIC?. An explanation is offered to the very strong dependence of the induction time on the cyanogen concentration and the very weak dependence on the oxygen concentration. The sensitivity spectrum shows that the induction time is highly dependent on the 0 + C2N2 -NCO + CN and NCO + M -N + CO + M reactions (shortened) and the 0 + NCO -CO + NO and N + NCO -N2 + CO reactions (increased).

## Abstract __A combined experimental and theoretical approach is used to study the thermal autoxidation of Ξ±βpinene. Four different types of peroxyl radicals are generated; the verbenyl peroxyl radical being the most abundant one. The peroxyl radicals propagate a long radical chain, implying that
Studies of the stoichiometry and kinetics of the reaction between hydroxylamine and iodine, previously studied in media below pH 3, have been extended to pH 5.5. The stoichiometry over the pH range 3.4-5.5 is 2NHzOH and k l , kz, Kp, and KI are (6.5 2 0.6) x lo5 M-' s-', (5.0 2 0.5) s-', 1 x lo6 M-
