Abstract

Combination reactions of the methyl radical have been studied by following the decay of the absorbance of the methyl radical during the course of the reaction by means of kinetic spectroscopy. The limiting values of the second‐order rate constants at high pressure were determined for two reactions at room temperature:
The extinction coefficient of the methyl radical was found to have a maximum value of (1.02 Β± 0.06) X 10^4^ 1 mole^βˆ’1^ cm^βˆ’1^ at 216.4 nm. Integration of the extinction coefficient over the absorption band of the methyl radical gave an oscillator strength of 1.0 X 10^βˆ’2^.

The reaction CHs+NO (+M) +CH,NO (+M) was initiated by pulse radiolysis of acetone/nitric oxide mixtures and the kinetics of methyl radicals was studied by time-resolved infrared absorption spectroscopy. The rate constant was found to be strongly pressure dependent in the range of p( M ) =6.5-150 mba

## Abstract Intrinsic spectral and kinetic parameters have been measured for the ethyl radical, which was formed in the gas phase by the flash photolysis of azoethane. Absolute values of the extinction coefficient Ο΅(Ξ») were derived from complementary measurements of the yield of nitrogen and the ab
