A FLASH-PHOTOLYSIS RESONANCE FLUORESCENCE INVESTIGATION OF THE REACTIONS OF OXYGEN O(P-3) ATOMS WITH ALIPHATIC ETHERS AND DIETHERS IN THE GAS-PHASE

Rate constants for the gas phase reCedex 2, Franceactions 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 −1 s−1): (Formula Presented.) 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 10−14 cm3 molecule−1 s−1): tetrahydrofuran (37.5 ± 1.1); 1,4−dioxane 1(6.81 ± 0.46); diethoxymethane (40.4 ± 1.8); ethyl ‐t‐butyl ether (37.0 ± 1.3); and methyl‐t‐amylether (57.3 ± 2.3).
