## Abstract The reaction of hydroxyl [OH] radicals with formaldehyde [CH~2~O] was studied at temperatures ranging from 934 K to 1670 K behind reflected shock waves at an average total pressure of 1.6 atm. OH radicals were produced by shockβheating tertβbutyl hydroperoxide [(CH~3~)~3~ο£ΏCOο£ΏOH], while

Kinetic model results are presented for desorption of OH radicals formed during the reaction HI + fOz+HzO on Pt. The results are compared with recent experimental results using laser-induced fluorescence. Variation in the apparent activation energy for OH desorption with HZ/O1 ratio can be attribute
The rate constants for the reactions OH(X 'II, kl k2 u=O) + NH3 --t HzO+ NH? and OII(X '11, u=O) + O3 -HO, + O2 were measured at 296K by the flash photolysis resonance fluorescence technique. The values of the rate constants thus obtained are kl = (4.1 +-0.6) X lo-l4 nndkz = (6.5 t 1.0) X lo-l4 in u
