✦ Synopsis

The recombination of methyl radicals generated by pyrolysis of azomethane-Ar mixtures and detected by coincidence absorption of the zinc 213.9 urn atomic line was studied in incident shock waves at temperatures from 1300 to 1700 K and densities from 2 X 1 Oe6 to 9 x 1 0e6 mol/cm3. A simultaneous regression analysis based upon large factorial design computer simulations was used to solve the inverse problem of parameter identification and to determine optimal values of rate coefficient and other parameters. The rate coefficient found for the recombination channel is in agreement with a previously published nine-parameter weak collision model.

## Abstract Rate constants are calculated for CH~3~ (+ Ar) ⇄ CH~2~ + H (+ Ar) at the limiting low‐pressure, the limiting high‐pressure, as well as the intermediate fall‐off ranges. The results show that published experimental rate constants for methyl dissociation correspond to the fall‐off region

The pyrolysis of 1 and 2% ethane in krypton has been studied in shock waves by the laser-schlieren technique over 1700-4800 K. For 2400-2800 K an effective zero density gradient is seen following the rapid dissociation of the ethane. Through simulation with various mechanisms it is evident that the

Spontaneous formation of free radicals at low temperatures (77-200 K) was investigated during fluorination and chlorination of polymers (polystyrene, lignin) and low-molecular weight phenols, as well as during interaction of sodium hydroxide with lignin.
