Abstract
The mass spectra of the compounds (C6F5)3 –nMPhn(n= 0–3; M = P and As), Ph3Sb, PhSb(C6F5)2, and (C6F5)3Sb have been studied. The basic features of the spectra of each type of compound are reported and correlated with the nature of the central atom, and compared with the analogous compounds for the Group IV derivatives where these have been studied. In general, there are few similarities between the mass spectra of Group IV and Group V derivatives. The fluorine-containing compounds exhibit characteristic migrations of fluorine to the central atom to give an increase in MF+, MF2 +, and RMF+(R = C6H5 or C6F5) ions on descending the group.Keywords
