摘要

As an analytical tool for determining double bond position, the data here suggest that sodium is most favourable since the [M - 2H + Alk]~-/[M - H]~- branching ratio is greatest for the 20:3-sodium fluoride complex. Furthermore, additional structurally information was not gained for other metal anionic complexes. The study of fatty acid-metal anionic complexes reveals interesting ion chemistry, for example, a triply deprotonated fatty acid ([M - 3H + Mg]~-) was observed in the CID spectrum of the [2(M - H) - H + Mg]~- ion.
