摘要：

Fast-atom bombardment desorption combined with mass spectrometry (using linked scans at constant B/E) of a lithium-cationized long-chain acetogenin was used to determine the position of two epoxy rings in the alkyl chain. Analysis of metastable and collision-induced dissociations gave structurally useful information which could not be obtained by other spectroscopic methods such as nuclear magnetic resonance. A direct effect of lithium on the observed decomposition pathways was demonstrated.
