Positive-ion, methane-mediated chemical ionization mass spectra were measured for simple bifunctional aromatic compounds of the type m-XCH2C6H4CH2Y, where X = NH2 and N(CH3)2, and Y = OH and OCH3.Essentially only three peaks of ions, +, + and +, have appeared for each compound.Since the two functional groups XCH2- and YCH2- do not interact with each other after protonation or after fragmentation, they are assumed to be protonated and to undergo fragmentation independently.The relative protonation susceptibility and fraction of fragmentating + can be estimated for each functional group in these compounds.A semi-quantitative interpretation of the observed spectra is presented.
