Abstract

The reaction between H and C~3~H~5~ 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 C~3~H~5~ ([H] ≪ [C~3~H~5~]), 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 ⩽ P/torr ⩽ 400; no clear pressure‐dependence is found in this range of pressures and the mean rate coefficient is (2.8 ± 1.0) × 10^−10^ cm^3^ 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.
