Copper-mediated peptide radical ions in the gas phase

Article Abstract:

Molecular radical cations, M(super .+), of amino acids and oligipeptides are produced by collision-induced dissociation of mixed complex ions, [Cu super II (dien)M](super .2+), that contain Cu super II, an amine, typically diethylenetriamine (dien), and the oligopeptide, M. The conclusion states that M (super .+) ion's fragmentation chemistries are rich, fascinating, and different from those of protonated peptides.

Time resolved EPR of excited triplet C60 aligned in nematic liquid crystals

Article Abstract:

Two narrow EPR lines are shown by triplet C60 in nematic phase of liquid-crystal E7. Time decay of TR-EPR signal is described by a kinetic model.
