✦ Synopsis

The decomposition of CH3CDzCH3 was studied from 713 to 853 K at pressures of 98-466 torr. The values of k l l k z = 2.08 f 0.05 and k3lk4 = 2.04 f 0.66 were found independent of temperature by measuring the ratios of C H ~C H J D and C H ~C H D Z / C H ~C D ~, respectively, for the following reactions:

(1)

(2)

Isomerization of CH3CDCH3 was detected by measuring CHDCHz formed from the isomerized radical. The expression of k2llkzz was found to be log(kz~/kzz) = 0.3 f 0.5 -(11 f 7 kJ/mol)/2.3RT where kzl and kzz are the rate constants of (21

The results and conclusions are discussed and compared with previous works.
