The electron impact ionization mass spectra of the p ‐carboxyphenylsulfonylamide (1), p ‐carbomethoxyphenylsulfonylamide (2), p ‐methoxyphenylsulfonylamide (3) and p ‐fluorophenylsulfonylamide (4), of O,O‐diphenyl‐thiophosphoric acid, are discussed and interpreted, based on accurate mass measurements and metastable ion analysis. The fragmentation pattern shows common features for all compounds. Some cleavage processes specific to the radicals bonded to the aryl site are observed in each spectrum. © 1998 John Wiley & Sons, Ltd.
