Experimental and theoretical studies on the charge stripping from CH3X+ and CH2XH+˙ ions (X = F, Cl, Br, I, OH, SH, or NH2)

Abstract

Charge stripping from aither Ch₂XH⁺˙ or CH₃X⁺˙ cation radicals (X = F, Cl, Br, I, OH, SH, or NH₂) results in the formation of ovservable dications; a comparison of experimentally derived Q_min data for the process m⁺→m²⁺ with the computed vertical ionization energies, I.E._v suggests that whereas electron removal from CH₂XH+· results directly in the formation of the corresponding dications, i.e. CH₂XH²⁺, charge stripping from CH₃Z⁺˙ does not lead to stable CH₃X²⁺ species, but instead rearrangement (perhaps from a Rydberg state of CH₃X⁺˙) is likely to take place to give CH₂XH²⁺ ions.
