Abstract :
Isomers of the C5H3 and C5H5 free radicals formed in benzene/oxygen flame are identified by analyzing the observed photoionization efficiency spectra with the aid of theoretical simulations based on calculated ionization energies (IEs) and Franck–Condon factors. For C5H3, the results reveal that two linear isomers (i-C5H3 and n-C5H3) are formed in the benzene flame, while, for C5H5, both linear and cyclic isomers (l-C5H5 and c-C5H5) are formed. Adiabatic IEs for i-C5H3, n-C5H3, l-C5H5 and c-C5H5 are measured to be 8.21, 8.32, 7.83 and 8.44 eV, respectively (all with an uncertainty of ±0.05 eV).
