The initial rates of formation of the major products in the thermal reactions of ethylene at temperatures in the neighborhood of 800 K have been measured in the presence and absence of the additives neopentane and ethane. It has been shown that in the absence of the additive the main initiation proc

Ab initio 3-31C + 3s RHF computations of the lowest escited state of the ethyl radical show that rhis species should be either directly dissociztive or predissochtive. There esists a direct excited-state surface taking zhe exited state adiabatically to the ground state of ethylene f H.

Reactions of the hydroxyl radical, OH, with several reactants have been studied near 1200 K in shock tube experiments in which UV absorption was used to monitor the OH concentration. The values of the rate coefficients were found to be 2.7 x lo", 2.6 X lo", 2.8 x and 1.26 x 1013 cm3/mol-s for the re
