Abstract

Abstract Collision-induced dissociation of mass-selected SiC 2X + 2 species (X = H, D), generated by electron impact ionization of ClSi(CX 3) 3 (X = H, D), gives rise to spectra which are consistent with the structure of the theoretically predicted cation radical of 3-silacyclopropenylidene ( 1 + ). This species can be successfully neutralized and reionized under the conditions of neutralization-reionization mass spectrometric experiments, thus supporting previous theoretical predictions that 3-silacyclopropenylidene ( 1) is a stable molecule in the gas phase. A description of the BEBE tandem mass spectrometer is given.
