β¦ Synopsis
The kinetics of the gas phase reactions of NO, with a series of organics have been studied at 295 ? 2 K. It was observed that only 2,3-dimethyl-2-butene and the conjugated dialkenes studied reacted at observable rates, with rate constants which ranged from 1.5 x lo-" cm3 molecule-' s-' for 2,3-dimethyl-2-butene to 1.3 x lo-'' cm3 molecule-' s-' for a-phellandrene. These rate constants are compared with the available literature data and the mechanisms of these reactions are discussed.

## 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
The rate law -d[O,]/dt = kl[A][OJ + k3[A][03]2/(k4 + kb[02]) has been found to obrain for the reaction of ozone with allene and with 1,2-butadiene. We now find that this rate law also applies to the reaction of ozone with ethylene and presumably with all lower alkenes. This generalizes the inhibiti
The thermal decomposition mechanisms of gaseous nitromethane, methyl nitrite, dimethylnitramine and 1,3,3,-trinitroazetidine (TNAZ) have been reanalyzed using sensitivity and principal component analyses. For each system an adequate, much simplified mechanism was developed, and the fragmentation/rea
