The mass spectra of some simple mixed alkyl, aryl, halo, secondary and tertiary phosphines, arsines and stibines

Abstract

A comparative investigation of the mass spectra of the compounds Me₂PhE, MePh₂E, MeEtPhE (where E = P, As or Sb), PhPrⁱEH (where E = N, P or As), MePhAsH, MePhEX (where X = Cl or I and E = As; X = Br and E = Sb) and PhPrⁱEX (where X = Cl and E = P or As) has been undertaken at 70 eV. The main fragmentation pathways have been determined and the criteria established for the interpretation of spectra of these simple derivatives applied to a series of more complex arsines.
