The distribution of small carbon clusters derived by laser ablation (laser desorption/ionization) of thin films of derivatised fullerenes has been studied. The production of positive and negative ions has been monitored by time-of-flight (ToF) mass s

Nine peptides containing highly basic residues were studied by post-source decay (PSD) in a reflectron time-of-flight (TOF) mass spectrometer. Although these compounds produced more abundant yields of protonated ions, [M+H] + , by matrix-assisted las

The formation of the nitrogen heterofullerene, C59N, following the ablation of a variety of fullerene derivatives, all of which possess organic ligands bound to the carbon cage through a nitrogen atom, has been investigated utilizing laser desorption

The molecular structures of tert -butyldimethylsilanol and its hemihydrate in the gas phase have been determined by electron diffraction. The two diffraction patterns are indistinguishable, indicating that the hydrate is essentially completely dissoc

The effects of the identity and position of basic residues on peptide dissociation were explored in the positive and negative modes. Low-energy collision-induced dissociation (CID) was performed on singly protonated and deprotonated heptapeptides of
