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 Qmin 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.
