Abstract

The reaction of SF6- with O-3 (1) has been studied at room temperature using a recently constructed flowing-afterglow apparatus. The measured rate constant is k(1) = (1.7 +/- 0.5) x 10(-10) cm(3) molecule(-1) s(-1), i.e. below the value calculated by the average dipole orientation theory and in disagreement with previous experimental data. Possible systematic errors have been rejected on the basis of kinetic results obtained in the same apparatus for the reactions of SF6- with NO2 (2) and Cl-2 (3), and for the reactions of O-3 with O-2(-) (4) and CO4- (5). The rate constants measured for these reactions are in agreement with previous determinations: k(2) = (1.5 +/- 0.7), k(3) = (1.1 +/- 0.3), k(4) = (6.3 +/- 2.0) and k(5) = (3.4 +/- 1.0), in units of 10(-10) cm(3) molecule(-1) s(-1).
