## Abstract Comparative studies of the ionisation potentials of some sydnones indicate that these molecules are largely present in the gaseous phase as their valence isomeric __N__‐nitroso ketenes.
## Abstract The ionisation potentials for a series of thiazolo[3,2‐a]pyridinium‐3‐oxides are reduced by about 1.7 to 1.8eV on introduction of an 8‐OH group. The gaseous species from the former compounds are ascribed a __mesoion__, structure while the hydroxy‐derivatives are rearranged to non charge
## Abstract Carnitine and its __O__‐acyl derivatives undergo two major pyrolytic reactions in the mass spectrometer. Firstly elimination of water from carnitine or acid from acylcarnitine takes place followed by intramolecular displacement and formation of crotonyl lactone and trimethylamine. Secon
