The unimolecularity of the thermal dehydrogenation of cyclopentene has been confirmed using the technique of very low-pressure pyrolysis (VLPP). Application of RRKM theory shows that the experimental unirnolecular rate constants obtained over the temperature range of 942O-1152OK are consistent with

Abstract
The decomposition of neopentane was studied using the veryβlowβpressure pyrolysis (VLPP) technique at temperatures from 1000 to 1260 K. The derived Arrhenius parameters
are consistent with Ξ΄__H__~f~^0^(tβbutyl) = 8.4 kcal/mol. Using the above A factor, data on the decomposition of tetramethyltin yield DH^0^(Sn(CH~3~)~3~ β CH~3~) = 69 Β± 2 kcal/mol.

## Abstract The thermal decomposition of __t__βbutylmethyl ether has been studied using the VLPP technique. The recommended Arrhenius parameters for the molecular elimination, reaction (1), are __A__(800Β°K) = 10^1 3, 9^ sec^β1^ and __E__~a~ (800Β°K) = 59.0 Β± 1.0 kcal/mole. No radical reactions occur
Studies of the kinetics of thermal unimolecular decomposition of methylcyclopentane, methylcyclohexane, ethynylcyclopentane, and ethynylcyclohexane have been carried out at temperatures in the range 861-1218 K using the technique of very lowpressure pyrolysis (VLPP). Multiple reaction pathways and s
The four species in the title were decomposed under VLPP conditions at temperatures in the vicinity of 1100Β°K. Three model transition states were constructed that fit the low-pressure data thus obtained and that also yield If EZSS = AEZSS; 2) &OO = A&oo; 3 ) log Alloo = 16.4 per C-C bond broken. Th
