Absolute rate coefficients for the reaction of H atoms and O atoms with formaldehyde were determined over the temperature range of 250 to 500 K. Linear Arrhenius behavior was observed in log(k/sub i/) vs 1/T plots for both reactions and the following rate parameters were obtained: k/sub 1/(T) = (3.27 +- 1.61) x 10/sup -11/ exp (-3670 +- 365/RT) cm/sup 3/ molec/sup -1/ s/sup -1/, k/sub 2/(T) = (2.78 +- 0.32) x 10/sup -11/ exp (-3030 +- 80/RT) cm/sup 3/ molec/sup -1/ s/sup -1/. Indicated error limits are two standard deviations. These results are compared with those of previous studies and are further discussed in terms of extrapolation to higher temperatures.
