title: Electron ionization-induced fragmentation of some new dibenzo(d, f)(1,3)dioxepine derivatives.
abstract: The mass spectrometric behaviour of a series of 6,6-disubstituted dibenzo(d,f)(1,3)dioxepine derivatives have been studied. The fragmentation patterns were described and discussed in detail with the aid of labelled compounds, accurate mass measurements and collisionally induced dissociation experiments performed using an ion trap.
