The reactions of the [2-2]-paracyclophane 1 and the [2-2]-metaparacyclopane 2 in the gas phase after protonation by CI(CH4) or CI(I-C4H10) were studied by FT-ICR mass spectrometry. The ions C16H17+ produced in the external ion source of the FT-ICR in
In the present and in the preceding article, the unimolecular fragmentation of the radical cations of 2-benzylindane and eleven derivatives bearing meta- or para-substituents at the benzylic moiety have been studied with respect to the hydrogen excha

The four dihalogeno phenylarsanes C6H5AsF2, 1, C6H5AsCl2, 2, C6H5AsBr2, 3, and C6H5AsI2, 4, produce in the 70eV-EI mass spectra by loss of a halogen atom abundant halogeno phenylarseniun ions C6H5As+-X, 1a(+)-4a(+). The further fragmentation reaction

The ion/molecule reaction of the radical cations of three isomeric bromobutenes (2-bromobut-2-ene 1, 1-bromobut-2-ene 2, 4-bromobut-1-ene 3) with ammonia were studied by Fourier transform ion cyclotron resonance spectrometry to reveal the effect of a
