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
