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 thhe 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 of thhe observed decomposition pathways was demonstrated.
