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
Rate constants for the quenching of Oz(lAg) by 2,3dimethyl-2-butene and triethylamine have been determined in a discharge-flow system when NO2 is added to eliminate atomic oxygen from the system.
