Energy transfer during dissociative charge-transfer reactions of ethylene with H₂⁺ and He⁺ ions

The near-adiabatic theory has been applied to the dissociative charge transfer of C₂H₄ with H₂⁺ and He⁺ ions. The results are consistent with the proposition that the appearance potentials of the fragment ions correspond to the electronic energy levels of the C₂H₄⁺ ion. The internal-energy distribution of the primary-product C₂H₄⁺ ion is obtained by plotting the relative abundance against the appearance potential for the various fragment ions. © 1976.
