## Abstract The kinetics of iodine dioxide (OIO) reactions with nitric oxide (NO), nitrogen dioxide (NO~2~), and molecular chlorine (Cl~2~) are studied in the gasβphase by cavity ringβdown spectroscopy. The absorption spectrum of OIO is monitored after the laser photodissociation, 266 or 355 nm, of

β¦ Synopsis
The third order r a t e coefficients for t h e addition reaction of C1. with NOz, C1 + NOz + M-, CINOz (ClONO) + M; K,, were measured to be k,(He) = (7.5 t 1.1) x cm6 molecule-2s-1 a t 298 K using the flash photolysis-resonance fluorescence method. The pressure range of the study was 15 to 500 torr He and 19 to 200 torr Nz. The temperature dependence of the third order rate coefficients were also measured between 240 and 350 K. The 298 K results are compared with those from previous low pressure studies. cm6 molecule-zs-l and kl(N2) = (16.6 * 3.0) x

The termolecular rate constant for the reaction C1 + NO, + M has been measured over the temperature range 264 to 417 K and at pressure 1 to 7 torr in a discharge flow system using atomic chlorine resonance fluorescence at 140 nm to monitor the decay of C1 in an excess of NO,. The results are ky = 9.
## Abstract The kinetics of the reaction between NO~2~ and ([14]aneN~4~)Ni^2+^ were determined by laser flash photolysis. The NO~2~ was generated in two independent reactions, one of which is based on the photochemistry of (NH~3~)~5~CoNO~2~^2+^, and the other on the photochemistry of HNO~2~/NO~2~^β
The reactions of C1 and Br atoms with HzOz have been studied in the range of 300-350 K using the very-low-pressure-reactor technique. It was found that metathesis to produce HX and H02 is the only significant process (199%). For the reaction of Br 2 Br + HzO2 + HBr + HOz k z (300 K) = 1.3 f 0.45 X a
## Abstract The reactants, products, and transition states of the CH~2~O + NO~2~ reaction on the ground electronic potential energy surface have been searched at both B3LYP/6β311+G(d,p) and MPW1PW91/6β311+G(3df,2p) levels of theory. The forward and reverse barriers are further improved by a modifie
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
