✦ Synopsis
The results of the OH( 2 R þ ) ! OH( 2 P) luminescence registration at 1000 6 T 6 2500 K and 2:0 P p P 0:3 atm during the ignition-combustion process behind incident shock waves in (2H 2 + O 2 ) + Ar mixtures were subjected to theoretical analysis. Experiments are interpreted in terms of kinetic problem with account of the electronically excited particles OH( 2 R þ ), O( 1 D), and O 2 ( 1 D), and the vibrational nonequilibrium of initial H 2 and O 2 molecules. Slow vibrational relaxation of O 2 molecules exerts essential influence on the chemical transformation process through the chain branching reaction H + O 2 !HO + O. The maximum luminescence moments calculated are in good agreement with observed ones.
