Abstract
The thermal unimolecular isomerization reactions of cycloheptatriene, and of methyl‐ , ethyl‐ , and isopropyl‐cycloheptatriene, have been studied over the temperature range 900–1400 K in shock waves. Even for these large molecules, falloff behavior has to be taken into account mainly due to weak collision effects. The limiting high pressurerate constantsk ∞ and the specific rate constantsk (E) are derived for use in later photoactivation experiments.Keywords
