… fragmentation capability of functional groups in chemical ionization mass spectrometry of simple bifunctional compounds. Semi??quantitative interpretation of spectra
Abstract Positive-ion, methane-mediated chemical ionization mass spectra were measured for simple bifunctional aromatic compounds of the type m-XCH 2 C 6 H 4 CH 2 Y, where X= NH 2 and N (CH 3) 2, and Y= OH and OCH 3. Essentially only three peaks of ions,[MH]+,[MH– XH]+ and [MH–YH]+, have appeared for each compound. Since the two functional groups XCH 2–and YCH 2–do not interact with each other after protonation or after fragmentation, ...
