✦ Synopsis

The quenching rate constants of 02('Ag) with n-butylamine, diethylamine, dipropylamine, dibutylamine, and tripropylamine have been determined in a discharge flow system. The rate constants are found to be (1.6 i . 0.2) x lo3, (8.5 2 0.6) X lo4, (9.8 ? 0.5) x lo4, (2.1 2 0.1) x lo5, and (8.6 2 0.5) x lo5 1 mol-' s-l, respectively. The rate constants are found to increase in the order, tertiary amine + secondary amine .--$ primary amine. The "inductive effect" of alkyl substitution is also found to increase the rate constant in a given series of amines.
