It was found that the most favorable reaction route was when the linear C3H3 • rather than cyclic was obtained, which is reasonable since it is more stable. The decomposition enthalpies of reactions 18-21 were determined to be 3.6, 5.4, 6.4 and 13.0 eV, respectively. The energies required for reactions 18-20 are likely to be found in our plasma and therefore, strengthens our suggestion that the Cp ligand can be further decomposed into smaller fragments.
