✦ Synopsis

4 low-temperature matrix isolation method has been developed which makes possible the isolation and detection of HO2 radicals from a gas-phase radical chain-reaction system conta-ining atomic H, 0 and O H radicals as well. The formation of HOt radicals is demonstrated in the rarified hydrogen flame. The same radicals are observed to exist during the slow oxidation reaction of hydrogen between the second and third inflammation limits.

The kinetics of accumulation of HO2, H202, and H20 has been studied as a function of total pressure, composition of reacting mixtures, temperature, and diameter and the treatment of the surface of the reaction vessel. I t has been established that in a reactor treated with boric acid, the concentration of HO, radicals is in the order of 10'2-10" particles/cm3. The kinetic relationship obtained confirms the necessity of including the following step in the mechanism of slow oxidation of hydrogen:

## Abstract The rate of hydrogenation of cyclohexene, catalyzed by CoH~3~(PPh~3~)~3~, has been measured under various conditions and, based on these data, a mechanism has been postulated. For the individual steps of the mechanism enthalpy and entropy differences have been determined. The interpreta
