✦ Synopsis

The reaction of atomic hydrogen with 02('Ag) has been investigated as a function of temperature, using a fast discharge-flow apparatus equipped for EPR detection of free radical species. The rate constant for the overall reaction was measured as (1.46 f 0.49) X 10-I' exp(-4000 f 200 cal/mol/RT) cm3/s. Evidence is presented which suggests that the reaction occurs principally via abstraction, H + 0z('Ag) -OH + 0, rather than via physical quenching, H + 02('Ag) -H + 02(X3Z,).

The same chemiluminescent spectrum of HNO was obtained in both the reaction systems of 0(3P) + CaHe + NO + 02 (\* A,)/02 and H + NO + 02( 'Ag)/Oa. The reaction mechanism for producing the excited HNO is proposed to be -HNO('A') + 02 ( 'Ag) + HNO(3A", + 0s (3X,) , HNOc3A") + 02 ('A,) --t HNO('A") +
