## Abstract Doubly charged ion mass spectra have been obtained for 11 organophosphorus compounds. Methane has been used as a target gas to increase the probability of single electron transfer collisions in the first fieldβfree region of an Hitachi RMUβ7L mass spectrometer. In general, the spectra o
he doubly charged [MI\*+, [M+1I2+ and [M-O]'+ ions are observed in the field ionhtion mass spectra of para substituted acetophenones. "he effect of the type of the substituent on the formation of the doubly charged ions is described.
