✦ Synopsis

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 Ag) and relative rate constants for the denctfvation of O2(1Ci) have been deduced.

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)
