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. The results indicate that in many previous determinations of rate constants for the quenching of 02(lAg)
molecules from a discharge have been analyzed by the emission of the infrared atmospheric (0.0) bancfat 12700 A and by the emission of the atmospheric (0,O) band at 7619 A due to the energy pooling reaction ## 202(1Agj -+02('Cs) + 02(%;) . Particular rate constants for the deactivation of 02(1 A

In a fast flow system mixtures of SOCI 2 with helium were passed through a microwave discharge and added downstream to a flow of metastable 02 (lAg) molecules. Chemiluminescence of the SO(IAg--aZg) (0,0) band was observed at 1.705 #m in addition to the already known (0,0), (0,1), (1,1), and (2,2) ba
