Abstract
1,5โcyclooctadiene or 4โvinylcyclohexene mixture diluted with argon was heated to temperatures in the range 880โ1230 K behind reflected shock waves. Profiles of IRโlaser absorption were measured at 3.39 ฮผm. From these profiles, rate constants k~1~ and k~2~ for the decyclization reactions 1,5โcyclooctadiene โ biradical and 4โvinylcyclohexene โ biradical were evaluated as k~1~ = 5.2 ร 10^14^ exp(โ48.3 __k__cal/RT) s^โ1^ and k~2~ = 3.5 ร 10^14^ exp(โ55.3 __k__cal/RT) s^โ1^, respectively. ยฉ 1993 John Wiley & Sons, Inc.
