Research output: Contribution to journalArticlepeer-review


Ion/molecule reactions, unimolecular dissociations and collisional activation spectra of the C4H4+-, cation have been studied to obtain information about the chemistry, and possibly structure (or structures), of this ion. Precursor molecules employed included 1-buten-3-yne (vinyl acetylene), pyridine, benzene and 1,5-hexadiyne. Some ion reactions involving neutral 1-buten-3-yne were also followed. The reactivity of C4H4+- formed by ionization of neutral C4H4 was observed to be the same as that of C4H4+- cations formed as fragments following dissociative ionization.
