摘要: Atomic resonance absorption spectroscopy (ARAS) was applied to measure S atoms, behind shock waves in COS/H2 pyrolysis or CS2/H2 photolysis systems. Both the of COS and CS2 used generate which subsequently reacts with H2 via reaction: The experiments were designed provide clear first-order conditions for reaction (R3); i.e., concentration exceeds that by at least a factor 100. The atom profiles obtained during highly diluted COS/H2/Ar mixtures analyzed computer simulations based on simplified mechanism using rate coefficient k3 as fitting parameter. groups covered temperature range 1257 K ⩽ T 3137 lead of: . © 1995 John Wiley & Sons, Inc.
