Abstract
The kinetic method was used for the quantitative determination of lith ium-cation affinities by Fourier transform ion cyclotron resonance. Th is method was applied to a series of XYSO and XYSO(2) compounds. Proto n basicities of the SO and SO2 compounds were also determined. When co mparison is made between Li+ basicities and proton basicities, a linea r regression encompassing XYSO and XYSO(2) families suggests that Limay be bonded in a similar way to the SO and SO2 moieties, that is, to only one oxygen on the latter. PM3 calculations support this hypothes is. (C) 1997 American Society for Mass Spectrometry.
