Abstract: The fragmentations of the product ions produced by the ion-molecule reaction of the halogeno-benzene (chlorobenzene, bromobenzene and iodobenzene) were studied using the collision-induced dissociation. The main product ions of the ion-molecule reaction of three kinds of halogeno-beneze include the dimeric ions, m/z(2M-X) ions and m/z(2M-2X) ions. The CID spectra of these ions were compared with that of the protonated bromodiphenyl and biphenyl. The formation mechanism and the structure of the product ions were obtained.

Key words: Chlorobeneze, Bromobenzene, Iodobenzene, Ion-molecule reaction, Mass spectrometry/mass spectrometry
