| Abstract: | In a recent study of tetrachloroethylene, the anion yield curves were analyzed using three published negative-ion Morse potentials. Unexpected ions at zero electron energy were explained by the "Trojan horse" mechanism. This communication also attributes formation of Cl(2)(-) at higher energies to a Trojan horse mechanism. Six new Morse potentials are calculated to account for the observed anion states. These combine all extant electron impact and attachment data. The electron affinity of the C(2)Cl(3) radical, 3.1(1) eV, and the C-Cl bond dissociation energy 4.0(1) eV are reported. |
