Experimental and theoretical studies on the charge stripping from CH ₃X⁺ and CH₂XH⁺· ions (X = F, Cl, Br, I, OH, SH, or NH₂)

Charge stripping from either CH₂XH⁺· or CH₃X⁺· cation radicals (X = F, Cl, Br, I, OH, SH, or NH₂) results in the formation of observable 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 CH ₂XH⁺· results directly in the formation of the corresponding dications, i.e. CH₂XH²⁺, charge stripping from CH₃X⁺· does not lead to stable CH ₃X²⁺ species, but instead rearrangement (perhaps from a Rydberg state of CH₃X⁺·) is likely to take place to give CH₂XH²⁺ ions.
