Abstract :
Principal possibility of organic compounds (OC) synthesis in the plasma torch of super-high-velocity (SHV) impact is demonstrated in laboratory modeling of this process. Configuration of electromagnetic fields in the plasma torch presumably can provide asymmetrical origin of isomers. In the nature, the proposed mechanism could have played important role at the prebiotic evolution stage. It could provide the synthesis, accumulation, and complication of OC formed in large-scale plasma torches generated by the SHV impact during the heavy meteor bombardment; presumably, it was acting from the beginning of the Earth formation independently on the presence (or composition) of the atmosphere, dustiness of the medium absorbing the solar irradiation, and temperature. Mechanismʹs universality ensures also the OC synthesis in the low-temperature interstellar clouds during SHV collisions of dust particles. Estimates show that the mechanism can be dominating due to its efficiency.
