## Abstract The mass spectra are reported for a series of tris(__p__βalkylaryl)phosphines and the corresponding phosphine oxides. The phosphines all give [M]^+Λ^ as the base peak except when the phenyl groups are not __para__ substituted. For the oxides [MβH]^+^ gives the base peak with one excepti
