pathway is followed in the ionization/excitation processes (“cationic reactions”) that follow from electron impact in mass spectrometry. The thermal and cationic reactions of the monomethyl and dimethyl esters of the phosphoric acids (R=H,R'= CH3 and R = R' = CH3, respectively, in -P(O)(OR)(OR')) are entirely analogous to those of the free dibasic acid.
