The hydrogenated silicon carbides SiC,H' ( ) are generated and characterized in the gas phase by neutralization-reionization mass spectrometry. The mass spectra are in keeping with a linear connectivity SiC,W and rule out the isomeric form HSiC;.
Neutralization of a beam of vinylidene anions, [ CH,-C] -., by xenon gives rise to a stable CIHz species, having a lifetime 2 0.4 us. Re-ionization with oxygen generates a species which is identified byits collisional activation mass spectrum as the vinylidene radical cation, [CH+Z] +..
