Abstract : The mass spectra of methyphosphonic difluoride and dichloride and N,N-dimethylaminophosphoroamide difluoride and dichloride and their sulfur analogs are presented. Fragmentation paths which lead to most of the intense peaks in these spectra are suggested. Metastable data support many of these proposed fragmentations. Mass determinations at a resolution of m/delta m of 2500 and isotope patterns positively identify some of the empirical formulas. Labile hydrogens, trivalent phosophorus structures in the excited ions, and extensive rearrangement are indicated by the data. (Author)
