## Abstract Atomic resonance absorption spectroscopy has been used to investigate the thermal decomposition of N~2~O by monitoring the formation of O atoms behind reflected shock waves in the temperature range 1490β2490 K and at total pressures from 58 to 347 kPa, by using the mixtures of N~2~O hig

β¦ Synopsis
The consumption of nitric oxide in the shock-heated nitric oxide, hydrogen, and argon system had been studied and modeled as the chain-branching process containing the reaction H + NO Through the computer simulation method the authors clarified the role of the initiation reaction HI + NO -H N O + H (kl) in the system and obtained the rate constants of kl and k3 as k i = 10 13~f0.15 exp (-55.2 kcal/RT) and k3 = 1013.7*0.15 exp (-48.7 kcal/RT) (cm3/mole.sec), respectively. k i was one order larger than the value obtained in the flame experiment by Halstead and Jenkins.
N + OH (k3) as a slow-branching step.

The photolysis of formamide vapor at 2062 has been studied in a flow system with results essentially similar to those obtained previously under static conditions and higher conversions. The rotating-sector technique has been applied to the radical-chain decomposition of formamide under conditions (3

## Abstract The reaction of S atoms with O~2~ was studied behind reflected shock waves applying atomic resonance absorption spectroscopy (ARAS) for concentration measurements of S and O atoms. S atoms were generated either by laserβflash photolysis (LFP) of CS~2~ or by the highβtemperature pyrolysi
