Pressure dependence of the methyl radical combination reaction
The effect of pressure on the methyl radical combination reaction was measured following the pressure dependence of the cross-combination reaction for methyl-ethyl or methyl-isopropyl pairs of radicals. These were produced by the photolysis of the corresponding azo-compounds. The method was found to...

| Sumario: | The effect of pressure on the methyl radical combination reaction was measured following the pressure dependence of the cross-combination reaction for methyl-ethyl or methyl-isopropyl pairs of radicals. These were produced by the photolysis of the corresponding azo-compounds. The method was found to be very suitable for this type of study and 'fall-off' curves at 15, 60, and 100° were determined. In the range of pressures studied (from a few torr to 0·005 torr) the kuni/k∞ ratio varied from 1·0 to 0·25. The results do not support a loose activated complex model for the methyl radical combination reaction. |
