✦ Synopsis

Absolute rate coeficients for the reactions of the hydroxyl radical with dimethyl ether i k , ) and diethyl ether ( k 2 ) were measured over the temperature range 295-442 K. The rate coefficient data, in the units cm3 molecule s-l, were fitted to the Arrhenius equationsk,(T) = (1.04 2 0.10) x 10-"exp[-(739 ? 67 calmol-')/RTl andk,iT) = (9.13 2 0.35) x lo-" exp[+(228 2 27 kcal m ~l -~) / R T l , respectively, in which the stated error limits are 20. values. Our results are compared with those of previous studies of hydrogen-atom abstraction from saturated hydrocarbons by OH. Correlations between measured reaction-rate coefficients and C -H bond-dissociation energies are discussed.
