A Multiquantum State-to-State Database for Dissociation in Air Plasmas

The modelling of dissociation in high-temperature plasmas, with translational temperature in excess of 1,000-2,000K, mandates the application of detailed state-resolved models. In fact, the traditional first-order approaches, such as the SSH theory, begin to fail, yielding overestimated rates and neglecting multiquantum transitions. The multiquantum Forced Harmonic Oscillator method has instead been considered for N$_{2}$ and O$_{2}$ diatom-diatom dissociation rates, whereas semiclassical rates recently published by the Bari group have been considered for N$_{2}$ and O$_{2}$ atom-diatom dissociation rates. Finally, Zeldovich rates for the formation of NO have been selected from the literature. The resulting model provides an improved simulation of the dissociation processes in air plasmas.
