Electron impact mass spectra of six isomeric compounds, namely perezone, isoperezone, α-pipitzol, β-pipitzol, β-isopipitzol and dihydroisoperezinone have been recorded. The proposed fragmentation pathways leading to the formation of a number of important daughter ions have been confirmed from the co
