ResumoThe reaction kinetics of NH2 with propylene is studied by flash photolysis in the temperature range 300-500K. The NH2 radicals are detected by resonance absorption, using a cw single mode dye laser. This method allows the detection of very small radical concentrations in a wide range of experimental conditions. The reaction of NH2 with propylene is fairly slow and seems to correspond to the addition process. The Arrhenius expression obtained is (E in kcal/mole):k(NH2 + C3H6) = 2.9 × 108 exp[-4.3(± 0.2)[RT]M−1s−1.
