Summary

  1. 1.

    In the early stages of the hydrogen-oxygen reaction (less than 10% H2 depletion) the electronic excitation of Na atoms and OH radicals and the vibrational excitation of OH and H2O exceed the equilibrium values.

     
  2. 2.

    A comparison of the efficiency of the various sources of sodium excitation in the induction period of the H2−O2 reaction shows that the sodium is excited in collisions with OH and H2O possessing a nonequilibrium reserve of vibrational energy.

     
  3. 3.

    The nature of Na excitation in the systems C2H2−O2 and H2−O2 is practically the same; the excitation of Na in CH4−O2 and H2−Cl2 mixtures is equilibrium in character.
