Electronic structures and structure-related molecular properties of reactants, intermediates, products, and transition states were explored at the BH&HLYP/cc-pVTZ level of theory. Methyl butanoate combustion produces a substantial amount of CO 2 prior to ignition ( t * = 1), in comparison to that of n -butane, which is typically ascribed to the effect of the methyl ester, or specifically fuel-bound oxygen.

We sought to capture the effect of this fuel-bound oxygen and conducted ROP analysis to elucidate the pathways .
