The reaction between C3H5 and O(³P) has been studied over the temperature range 300-600 K by using two time-resolved techniques: laser flash photolysis of C3H5Br/SO2/He mixtures at 193 nm with detection by photoionization mass spectrometry, and laser flash photolysis of C6H10/N2O/N2 mixtures at 193 nm using absorption spectroscopy and resonance fluorescence to detect C3H5 and O, respectively.A temperature and pressure (2-350 Torr) independent rate constant of (3 +/- 1) x 10^-10 cm³ molecule^-1 s^-1 was obtained.Acrolein was the only product detected by photoionization mass spectrometry, suggesting that the major channel is C3H5 + O -> C3H4O + H.
