Pure coincidence? A combination of mass spectrometric experiments with multicoincidence detection and quantum chemical calculations has been used to unravel the fragmentation mechanisms of the neuroinhibitor γ-aminobutyric acid in the gas phase. Singly charged cyclic structures play an important role in the fragmentation, which preferentially takes place at the CβCγ bond (see figure).
