Formation of Excited Molecules from Fragments Formed in Heterogeneous-Homogeneous Processes in the Near-Surface Layer and Their Impact on Oxidation Processes

This study focuses on the formation of excited molecules and their significant role in influencing dynamic regimes of low-temperature oxidation, particularly in the context of methane and acetaldehyde reactions. The investigation reveals how quantum resonance facilitates the formation of excited formaldehyde molecules, driving energy transfer processes that influence radical chain reactions and inhibit oxidation. These processes lead to the formation of weak shock waves, which emerge due to the interaction of water complexes with negative halogen ions and the self-decomposition of ozone. Using theoretical modeling, computer simulations, and spectroscopy, the study uncovers the role of quantum resonance in generating weak shock waves and establishing oscillatory regimes. These findings contribute to a deeper understanding of the mechanisms of low-temperature oxidation and the complex interactions of excited molecules, offering new applications in both scientific research and industry.
