摘要：

The reaction between H and C3H5 has been studied at 291 K. Exciplex laser flash photolysis at 193.3 nm of hexa-1,5-diene-He mixtures generated both H and C3H5 ([H] << [C3H5]), which were detected in time-resolved mode by resonance fluorescence and absorption spectroscopy, respectively. Rate coefficients are presented at four pressures in the range 98 less-than-or-equal-to P/torr less-than-or-equal-to 400; no clear pressure-dependence is found in this range of pressures and the mean rate coefficient is (2.8 +/- 1.0) x 10(-10) cm3 molecule-1 s-1. Calculations based on the Troe factorization method confirm that this reaction is near its high-pressure limit under the experimental conditions.
