The reaction between C{sub 3}H{sub 5} and O({sup 3}P) has been studied over the temperature range 300-600 K by using two time-resolved techniques: laser flash photolysis of C{sub 3}H{sub 5}Br/SO{sub 2}/He mixtures at 193 nm with detection by photoionization mass spectrometry, and laser flash photolysis of C{sub 6}H{sub 10}/N{sub 2}O/N{sub 2} mixtures at 193 nm using absorption spectroscopy and resonance fluorescence to detect C{sub 3}H{sub 5} and O, respectively. A temperature and pressure (2-350 Torr) independent rate constant of (3 {plus minus} 1) {times} 10{sup {minus}10} cm{sup 3} molecule{sup {minus}1} s{sup {minus}1} was obtained. Acrolein was the only product detected by photoionization mass spectrometry, suggesting that the major channel is C{sub 3}H{sub 5} + O {yields} C{sub 3}H{sub 4}O + H.
