Dissociation of Molecular Nitrogen in the Absence of Vibrational Equilibrium,
Abstract
The measurements of the rate constants of the dissociation of nitrogen conducted up to the present time led to results which are distinguished sometimes even by an order of magnitude. This can be connected with the fact that the assumption about the equality of the translational and vibrational temperatures in the zone of dissociation is not made at high temperatures. In this work the dissociation of nitrogen, taking into account the effect of the incompleteness of vibrational relaxation is experimentally studied. The experiments were conducted in a shock tube with an inside diameter of 50 mm. Direct measurements were made of the concentration of atomic nitrogen appearing in the process of the dissociation of the molecules behind the shock-wave front. The measurement of the concentration of molecules and atoms of nitrogen was conducted by the method of absorption spectroscopy.
