The unimolecular decomposition of 3,4dihydro-2H-pyran was investigated behind reflected shock waves by monitoring infrared absorption at 9.44 pm. The decomposition proceeded via a direct molecular process to ethylene and acrolein. The Arrhenius expression for the decomposition rate constant, k= IO"-

The dissociation of NzO/Ar mixtures, with and without added CO, has been studied by monitoring both infrared and ultraviolet emissions behind reflected shock waves. Initial temperatures ranged from 1850 to 2535"K, and the total concentrations were 1.94-2.40 X 10'8 molecule/cm3. The infrared emission
The pyrolysis of benzene was studied in the temperature and pressure range of 1400-2200K and 0.25-0.81 arm using a shock tube coupled to a time-of-flight mass spectrometer. The mixtures employed were 2.1 and 5% benzene diluted with neon, which yielded a carbon atom density range of (1.6-7.9) x 1017
The thermal decomposition of acetylene has been studied in the temperature and pressure regimes of 1900-2500 K and 0.3-0.55 atm using a shock tube coupled to a time-of-flight mass spectrometer. A series of mixtures varying from 1.0-6.2% CzHz diluted in a Ne-Ar mixture yielded a carbon atom density r
The rate constant of the NF3 dissociation reaction in a helium mixture in the low-pressure limit was directly measured in a shock tube by a UV absorption method. The rate constant may be expressed as K= 10'4~3s~0~07 exp{-[36600+2100 (cal/mol)]/ RT) cm3/mol s in the temperature range 1050-1600 K. Lev
## Abstract Chemical kinetic simulations that more accurately consider reaction conditions behind reflected shock waves in a high pressure shock tube have been conducted by accounting for (1) timeβdependent temperature and pressure variations in contrast to assuming constant temperature and pressur
