## Abstract The rate constant for the bimolecular combination of benzyl radicals in cyclohexane and toluene is determined as a function of temperature. Further, it is studied in cyclohexaneβtoluene mixtures of different compositions. In the entire range covered, 9.8 Γ 10^8^ β©½ 2__k__~t~ β©½ 9.0 Γ 10^9

Rate constants for the reaction of CN( u= 0) with Cl,, FZ and O2 have been measured. CN radicals were generated by photolysis of C2Nz with pulsed radiation at 193 nm. Laser-induced fluorescence (LIF) was used to monitor the decay profiles of CN radical concentrations. The valuesobtainedare: k(CN/CI?
Relative rate constants for the reactions of hydroxyl radicals with a series of alkyl substituted olefins were measured by competitive reactions between pairs of olefins a t 298 r 2 K and 1 atmospheric pressure. Hydroxyl radicals were produced by the photolysis of H,O, with 254-nm irradiation. The o
The thermal decomposition of ethyl peroxynitrate was studied in a 420 !2 Dural glass reaction chamber in the presence of different initial [NO\*]/ [NO] ratios. From an analysis of the data, the following rate constant ratios k2/kl for the reactions of C2H502 radicals with NO (k,) and NOI (kz) were d
Absolute rate constants and thzir temperature dependence were determined by time-resolved electron spin resonance for the addition of the radicals PhcH, and PhcMe, to a variety of alkenes in toluene solution. To vinyl monomers CH,=CXY, PhCH, adds at the unsubstituted C-atom with rate constants rangi
