Evidence for a difference in the dissociation mechanisms of acetylene (HCCH) and vinylidene (H$$_{2}$$C=C:) from charge inversion mass spectrometry

Hayakawa, Shigeo*; Tomozawa, Koji*; takeuchi, takae*; Arakawa, Kazuo; Morishita, Norio

The process of formation of the negative ions in charge inversion mass spectrometry is via near-resonant neutralization followed by spontaneous dissociation, and then endothermic negative ion formation. The intensity of the C$$_{2}$$$$^{-}$$ peak relative to the C$$_{2}$$H$$^{-}$$ peak in these spectra increased with decreasing ionization potential of the targets for both of the isomeric C$$_{2}$$H$$_{2}$$$$^{+}$$ cations. The formation of the C$$_{2}$$$$^{-}$$ anion is proposed to result from the dissociation of excited C$$_{2}$$H$$_{2}$$ neutrals into C$$_{2}$$ and H$$_{2}$$. The dependence on target species of the intensities of C$$_{2}$$$$^{-}$$ peak relative to the C$$_{2}$$H$$^{-}$$ peak for HCCH and H$$_{2}$$C=C: cannot be rationalized by the internal energy of the excited C$$_{2}$$H$$_{2}$$ neutrals. The differences indicate that the isomeric C$$_{2}$$H$$_{2}$$ neutrals dissociate into C$$_{2}$$H and H prior to 1,2-hydrogen atom migration.
