^aSpecies symbols CYC₆H₁₀, CYHEXDN13, and CYHEXDN14 denote cyclohexene, cyclohexa-1,3-diene, and cyclohexa-1,4-diene, respectively. The CYC₆H₉-R1, CYC₆H₉-R2, and CYC₆H₉-R3 denote the three fuel radicals formed from abstraction reactions at the vinylic, allylic, and secondary alkyl sites, respectively.

^bRate coefficients are in the modified Arrhenius formula as k = ATⁿ exp(−E_a/RT). The units are cm³, mol, s, and K.
