Electronic and vibrational excitation in reactions of hydrogen with oxygen at high temperatures

  • 20 Accesses

Conclusions

  1. 1.

    The reaction of hydrogen with oxygen (H2∶O2∶Ar=2 ∶1∶60) in shock waves at the temperature 1190–1390°K and pressures 1–3.5 atm is accompanied at the early stages of the reaction by a substantial superequilibrium vibrational excitation of OH radicals and water molecules and electronic excitation of OH radicals and sodium atoms.

  2. 2.

    During the induction period the electronic excitation of OH is due chiefly to the reaction H+H2+O2→OH*+H2O, while at higher pressures it is also determined by the recombination of O and H. The following reactions are the most probable for an explanation of the vibrational excitation of water molecules: HO2+H2→ H2O *+OH and OH+H2→H2O*+H.

  3. 3.

    Superequilibrium electronic excitation of Na atoms apparently occurs in collisions with OH and H2O possessing a sufficient reserve of vibrational energy.
