The total rate constant for the reaction of CI atoms with H 0 2 N 0 2 was found to be less than 1.0 x cm3 5-l a t 296 K by the discharge flowiresonance fluorescence technique. The reaction was also studied by the discharge flowimass spectrometric technique. k , , + klb was measured to be (3.4 f 1.4)
The kinetics and mechanism of the reaction Cl Ο© HO 2 : products (1) have been studied in the temperature range 230-360 K and at total pressure of 1 Torr of helium using the discharge-flow mass spectrometric method. The following Arrhenius expression for the total rate constant was obtained either fr
The rate constant for the reaction (I), C1+ HOz -HCI + 0 2 , was measured using molecular modulation spectrometry to investigate HOz radical kinetics in the modulated photolysis of ClyH2-02 mixtures at 760 torr pressure. HOz was monitored directly in absorption at 220 nm, and k l was determined from
Fourier transform infrared spectroscopy was used to identify CH2CIOOH and HC(O)CI as products of the gas phase reaction of CH2CIO 2 radicals with HO 2 radicals. At 700 Torr and 295 \_ 2 K, branching ratios of kla//kl = 0.27 \_+ 0.05 and klb/k ) ffi 0.73 \_+ 0.12 were obtained for the CH2CIOOH formin
