A characteristic (singles) mass spectrum of SiCl4 following electron ionization at 200 eV.
Representative “pairs” mass spectrum of SiCl4 recorded at 200 eV showing observed ion pairs formed via charge-separating dissociation of SiCl4 2+ and SiCl4 3+.
Relative PICS σ r [X+] for forming ion fragments: (a) SiCl3 + (●), Cl+ (◆), SiCl+ (▪); (b) Si+ (●), SiCl2 + (▪), Cl2 + (◆); (c) SiCl2+ (◆), SiCl2 2+ (●), Si2+ (▪), Cl2+ (▲); following electron ionization of SiCl4. The corresponding relative PICS extracted from the data of Basner et al. (Ref. 20) (open symbols) are also shown.
Relative precursor-specific PICS σ n [X+] for forming monocation fragments via dissociative single (−●−), double (–▪–), and triple (··▲··) electron ionizations of SiCl4.
Relative precursor-specific PICS σ n [X2+] for forming dication fragments via dissociative double (▪) and triple (▲) electron ionizations of SiCl4.
Contributions to the total ion yield from single, double, and triple ionization, following electron ionization of SiCl4.
Summary of the precursor-state energies for ion pair formation following charge-separating decay of SiCl4 2+ determined in this work.
Geometric parameters for the minima of SiCl4 2+ located computationally. Energies E relative to the ground state of SiCl4 are also given. See text for details.
