Upper limits of and were established for 4 Ο« 10 7 Ο« 10 cm molecule s the gas-phase reactions of H 2 O 2 with O 3 and NO, respectively. These reactions are too slow to explain features observed in the atmospheric vertical profile of H 2 O 2 .
## Abstract The fast flow method with laser induced fluorescence detection of CH~3~C(O)CH~2~ was employed to obtain the rate constant of __k__~1~ (298 K) = (1.83 Β± 0.12 (1Ο)) Γ 10^10^ cm^3^ mol^β1^ s^β1^ for the reaction CH~3~C(O)CH~2~β+βHBr β CH~3~C(O)CH~3~β+βBr (1, β1). The observed reduced react
The rate constants of the reactions of ethoxy (C 2 H 5 O), i-propoxy (i-C 3 H 7 O) and npropoxy (n-C 3 H 7 O) radicals with O 2 and NO have been measured as a function of temperature. Radicals have been generated by laser photolysis from the appropriate alkyl nitrite and have been detected by laser-
