“…For a comparison, the strength intensity of the lightning electric field is 3 × 10 6 V/m (30 kV/cm) under dry air condition, at atmospheric pressure [37,38]. The methods of measuring of these strength fields are described in [39]. The project ELI-NP was promoted by Professor Gérard Mourou in 2006 [40], one of the winners of the Nobel prize in physics 2018 [41].…”

“…The lightning flash provides the formation of NO 2 molecules, which are significantly related to the biological efficiency and ozone chemistry in the troposphere, and the shock wave, which emits heat needed for many chemical reactions to occur, and a radiation source with a broad electromagnetic spectrum from gamma rays to infrared spectrum, and even fission and fusion reactions. Another important effect in such a system is the electric field, the size of which ranges from a few thousand to 10 8 V/m − and is perpendicular from the clouds to the ground. That is why, lightning strikes include science in many branches of physics.…”

Unlike the compounds of the natural air atmosphere, the lightning systems are primarily focused on NO(X2Π), NO2(12A′), and O(3P) concentrations that occurred newly and highly in the ground electronic structure. While the NO/NO2 concentrations ratio is about 2000 during the lightning flash, this ratio becomes about 0.8 right after the lightning flash. The reason for this decrease in the ratio is the disappearance of the high temperature that prevents the formation of NO2 (with the combination of NO and O) and of the photon energy that causes its dissociation (NO2 + hv → NO + O) right after the lightning flash. However, this study will focus on the reactions that contribute to the NO concentration, except for the combination of N and O atoms during lightning flash. To do this, it was focused on the reactive scattering states (especially the NO-exchange) of the NO + O collision and the photo-dissociation of NO2, which provide the formation of the NO molecule in the ground electronic state. This case raises important questions. To what extent do the NO-exchange reaction and the photo-dissociation of NO2 contribute to the atmospherically observed NO molecules? or how can the vibrational quantum states of the NO molecules formed by the photo-dissociation be effected on the NO + O1 collision to produce a NO1 molecule? These conditions may contribute to the concentrations of NO high during lightning flashes. Under low collision energy (between 0.1 and 0.3 eV), the NO (v = 0) population dissociated by a photon can act as reactants in the NO-exchange reactive scattering on the doublet electronic state. Since it is assumed that all of the NO2 molecules are due to NO in the lightning flash system, this is one of the reasons that makes the NO population so high during lightning flash. Therefore, in the light of considering that the lightning system supports the formation of highly vibrating molecular groups, it might also support the formation of O2 molecules. In particular, it was shown that the v = 4 quantum state of the NO molecule over the doublet state between collision energies of 0.9–1.5 eV and the v = 5 quantum state of the NO molecule over the quartet state between collision energies of 1.0–1.5 eV contribute to O2 formation.

“…In addition, width of the electric field can be up to range of several km [Jacobson and Streets, 2009;Coleman et al, 2003]. In the open and clean air, the electric field power is 20-30 V/m and in the lightning-free cloudy environments it is around 800 V/m (Larossi et al, 2011). Unlike the above mentioned electric fields, in positive and negative Corona discharge events, it can occur under high electric field, from 10 6 to 10 8 V/m (1 a.u.…”

The focus in this study is on the formation of the NO2 molecule on the O+NO system, which is the atom-diatom reaction that occurs the most according to the molecular concentrations formed as a result of lightning flashes. In this study, it was mentioned that another external effect that affects NO2 molecule concentrations, other than temperature and visible electromagnetic radiation, is the electric field. This will suppress the formation of O2 at high temperatures and the formation of NO concentration at low temperature, as it increases the barrier in the product channel on the reaction pathway and NO+O recombination in the reactant channel under favorable conditions. Under these two conditions, the NO2 population might be supported by electric field.
