✦ Synopsis
The collision-induced dissociation characteristics of the beazyl, tropyl and tolyl cations which sewe to identify these [C,H71+ isomers (the m/z 74-77 relative abundance@ were not preserved in their neutralizatiou-reionization (NR) mass spectra. However, analyses of mixtures of the [C,H,]+ isomers made by comparison of NR maw spectra gave similar results to those obtained from collisionnl activation (CA) maw spectra. The radicals produced by electron transfer from Xe to tolyl cations were not obsewed to rearrange to benzyl radicals on the time-scale of the NR experiment, a result in conflict with other gas-phase studies.
' Ratio from CA mass spectrum. * CH, chemical ionization to generate [C,H,]+ via HF loss.
