β¦ Synopsis
Measurements of the effective rate constants for the reaction C$+OH were carried out in N,/O* or ArjOs mixtures at atmospheric pressure with different O2 partial pressures. In order to explain the difference between the results obtained from absolute and relative rate techniques a mechanism has been developed which proposes the regeneration of OH radicals during the oxidation of CS?.

The rate constant k , for the reaction of OH radicals with C102 molecules was measured in a discharge flow system over the temperature range 293 5 T < 473 K and at low pressures, 0.5 5 P 5 1.4 torr, using electron paramagnetic resonance or laser-induced fluorescence to monitor the pseudo first-order
The reaction of OH radicals with CS2 has been investigated by the application of Fourier transform infrared spectroscopy using both photolytic and nonphotolytic competitive techniques in a 420-L reaction chamber at different pressures over the temperature range of 264-293 K. The measured effective r
## Abstract A new mechanism for gas phase ozoneβolefin reactions is proposed. The mechanism involves biradical intermediates which can react in a variety of ways. One of the possible reaction modes corresponds to the Criegie mechanism originally proposed to explain solution ozonolysis reactions and
