ABSTRACT
Hydroxylamine complexes display internal dynamics that are not generally observable with similar peroxo complexes. There is the possibility of end-for-end rotation of the hydroxylamine group. This rotation gives rise to isomers that, in principle and in practice, are observable. In fact, for the imidazole complexes, dynamics studies have shown there is rapid exchange between the various isomeric complexes that arises from end-for-end rotation of the hydroxylamine groups and from imidazole dissociation and reassociation [2].
