Abstract

Reactive endothermic collisions between N-acetylated oligosaccharides and ammonia have been carried out at very low beam energies. At energies slightly above those for which the proton collision complex Is observed, the major fragment ions include those resulting from cleavages localized at the amide bond. At somewhat higher energies, localized fragmentation gives way to cleavages of the glycosidic bond. Such studies Indicate that fine tuning of the beam energy can be employed for site-directed fragmentation in endothermic collision complexes.
