  Matrix isolation electron spin resonance studies of silicon (28,28Si2+, 28,29Si2+, 29,29Si2+) and germanium (Ge2+ and 73Ge2+) cations produced by pulsed laser vaporization. Comparison with theoretical calculations

  摘要：

  The Si2+ and Ge2+ cation radicals were generated by pulsed laser vaporization and isolated in rare-gas matrices at 4 K for electron spin resonance (ESR) investigations. The electronic ground states were established as X4-SIGMA for both cations with the three unpaired electrons occupying predominantly valence p-type orbitals. In the case of Si-29(2+), the observed nuclear hyperfine interaction (A tensor) was compared with that computed in an ab initio configuration interaction type calculation. The dependence of the hyperfine parameters on internuclear distance was also investigated. For comparison purposes, all diatomic and triatomic cations studied in the gas phase and in rare-gas matrices at sufficiently high resolution to observe nuclear hyperfine interaction are listed. For Si-29(2)+ in neon, g perpendicular-to = 1.993 (1), (A perpendicular-to ) = 52.4 (5) MHz, and D = 27.6 (8) GHz; for Ge-73(2)+, g perpendicular-to = 1.939 (1) and (A perpendicular-to ) = 10 (3) MHz.

  Anionic and cationic silicon clusters react exothermically with WF6 to give a variety of tungsten and silicon fluorides. All the silicon anionic clusters transfer their charge to WF6. The electron affinities of Si2–6 are estimated to be less than the electron affinity of WF6 (350 kJmole (3.6 eV)).
