abstract

  • AbstractCollisional activation spectra were used to characterize isomeric ion structures for [CH5P]+˙ and [C2H7P]+˙ radical cations and [C2H6P]+ even‐electron ions. Apart from ionized methylphosphane, [CH3PH2]+˙, ions of structure [CH2PH3]+˙ appear to be stable in the gas phase. Among the isomeric [C2H7P]+˙ ions stable ion structures [CH2PH2CH3]+˙ and [CH2CH2PH3]+˙/[CH3CHPH3]+˙ are proposed as being generated by appropriate dissociative ionization reactions of alkyl phosphanes. At least three isomeric [C2H6]+ ions appear to exist, of which \documentclass{article}\pagestyle{empty}\begin{document}$ {\rm CH}_{\rm 3} - \mathop {\rm P}\limits^{\rm + } {\rm H = CH}_{\rm 2} $\end{document} could be identified positively.
