It is shown that the y-or 1,s-hydrogen shift in the molecular ion of 1-nitropropane leads to three primary fragmentation reactions. They are the loss of a hydroxyl radical, a molecule of ethylene and a molecule of nitric oxide. The structures and chemistry of the resulting ions have been investigate
## Abstract The mechanistic aspects of alkene loss from ionized ethylβand __n__βpropyl phenyl thioethers have been studied by use of deuterium labelling and tandem mass spectrometry. Loss of ethene from the molecular ion of ethyl phenyl thioether proceeds predominantly by a specific Hβshift from th
