Spectral fingerprints: Collision-induced dissociation (CID) of protonated peptides in the gas phase results in linear fragment ions with a five-membered oxazolone ring on their C-terminal side. Infrared spectroscopy confirms that smaller fragments adopt oxazolone structures. Conversely, in mid-sized and larger fragments an isomerization to "head-to-tail" macrocycles is observed (see picture).
