Potential Energy Surface for Oxidation of Indenyl C9H7

Resumo

Ab initio calculations were performed to obtain local energy extrema, including an effect of reagents, intermediates, and reaction products on the potential energy surface for the C₉H₇+O₂ reaction, playing a significant role in oxidation of polycyclic aromatic hydrocarbons at combustion conditions. The final products, determined as a result of the calculations are styrenyl radical C₈H₇+CO₂, ortho-vinyl phenyl radical C₈H₇+CO₂ and 1-H-inden-1-one C₉H₆O+OH, which is predicted to be the prevailing reaction product.
