✦ Synopsis

Rate constants for the gas phase reactions of O(3P) atoms with a series of symmetric aliphatic ethers have been determined using the flash photolysis resonance fluorescence technique over the temperature range 240-400 K. The Arrhenius parameters derived from these data are (in units of cm3 molecule-' s-l):

The error limits are two standard deviations derived from the least-squares fit. Rate constants for several other ethers were determined only at 298 K. The values obtained were (in units of cm3 molecule-' s-l): tetrahydrofuran (37.5 2 1.1); 1,4-dioxane (6.81 2 0.46); diethoxymethane (40.4 2 1.8); ethyl-t-butylether (37.0 2 1.3); and methyl-t-amylether (57.3 ? 2.3).
