Abstract Ion‐structure investigation of the [MH] + ions from chalcone has been carried out by collision experiments performed with an ion‐trap mass spectrometer (ITMS), operating with the application of a supplementary RF voltage. The data so obtained, together with those achieved by comparison with labelled model compounds, have led to a clear identification of the [MH] + ion structure, proving the high potentialities of the ITMS in such a field.
