| Abstract: | Fragmentation of electron-impact-generated organic molecular cations, submitted to low-energy collisions with hydrogen in a MS/MS/MS multiquadrupole mass spectrometer, was promoted or significantly increased in the presence of atomic hydrogen generated from a microwave discharge. Loss of hydrogen alpha to a heteroatom and bond cleavage alpha to a carbonyl group are the major H-induced fragmentation pathways. |
