Dissociative Electron Attachment to Hexachlorobenzene.

Gas phase molecules of hexachlorobenzene (C6 Cl6 ) were investigated by means of dissociative electron attachment spectroscopy (DEAS). Three channels of molecular negative ions decay have been identified: abstraction of Cl- and Cl2 - as well as electron detachment (τa ∼250 μs at 343 K). All three channels exhibit temperature dependence. The adiabatic electron affinity estimated using a simple but typically accurate Arrhenius model (EAa =1.6-1.9 eV) turns out to be much higher than the quantum-chemical predictions (EAa =0.9-1.0 eV). We discuss the possible reasons behind the observed discrepancy. © 2022 Wiley-VCH GmbH.
