Generation of the m/z 69 ion C3HO2+ by electron ionization of some aryl-substituted β-diketones

The m/z 69 ion, prominent in the electron ionization (EI) mass spectra of some aryl-substituted β-diketones, has been shown to have the composition C3HO2+ by accurate mass determination, identification of its precursor ions, and of its decomposition product ions. In contrast, it is a minor ion in th...
