Ionization of large homogeneous and heterogeneous clusters generated in acetylene-Ar expansions: Cluster ion polymerization
Original language description
Pure acetylene and mixed Ar-acetylene clusters are formed in supersonic expansions of acetylene/argon mixtures and analysed using reflectron time-of-flight mass spectrometer with variable electron energy ionization source. Acetylene clusters composed ofmore than a hundred acetylene molecules are generated at the acetylene concentration of approximate to 8%, while mixed species are produced at low concentrations (approximate to 0.7%). The electron energy dependence of the mass spectra revealed the ionization process mechanisms in clusters. The ionization above the threshold for acetylene molecule of 11.5 eV results in the main ionic fragment progression (C2H2)(n)(+). At the electron energies }= 21.5 eV above the CH+CH+ dissociative ionization limit ofacetylene the fragment ions nominally labelled as (C2H2)(n)CH+, n }= 2, are observed. For n {= 7 these fragments correspond to covalently bound ionic structures as suggested by the observed strong dehydrogenation [(C2H2)(n) - k x H](+) an
