Oxidation of norbornadiene: Theoretical investigation on H-atom abstraction and related radical decomposition reactions

Propulsion and Power Research, 2023
The chemical kinetics of hydrogen atom (H-atom) abstraction reactions from norbornadiene (NBD) by five radicals (H, O(3P), OH, CH3, and HO2), and the unimolecular reactions of three NBD derived radicals, were studied through high-level ab-initio ...

Ab initio chemical kinetics of Isopropyl acetate oxidation with OH radicals

Green Chemistry Letters and Reviews, 2023
Global reactivity descriptors of isopropyl acetate (IPA) and thermo-kinetic aspects of its oxidation via OH radicals have been studied. Transition state theory (TST) was utilized to estimate the bimolecular rate constants.
