✦ Synopsis

Post-source decay (PSD) matrix-assisted laser desorption/ionization time-of-Ñight mass spectra were found to be useful for the structural elucidation of a series of tris [ 2-(glycosylthiourylene)ethyl ] amines. The reported fragmentation behaviours of [ M + H ] ', [ M + Na ] ' and [ M Ô H ]ions di †er from each other signiÐcantly ; however, they can be compared to tree pruning in every case. Whereas detailed structural information on unprotected glycoclusters is obtained from all PSD experiments, only the positive-ion mode can be used to gain relevant information about the acetylated glycoclusters.
