Abstract
As part of an investigation on the coordination ability of peptides, structural analyses of the solid di-, tri, and tetrapeptides glycyl-glycine (GG), glycyl-glycyl-glycine (GGG), glycyl-glycyl-glycyl-glycine (GGGG), and their protonated hydrochlorides glycyl-glycine.HCl (GGH), glycyl-glycyl-glycine.HCl (GGGH), and glycyl-glycyl-glycyl-glycine.HCl (GGGGH) have been carried out. The quantum chemical calculations (Hartree-Fock/6-31++G**) and linear-dichroic infrared (IR-LD) spectroscopy predict a near to linear structure of the pure ligands, but the experimental IR-LD data are in accordance with a cross-linked disposition of amide fragments in the protonated forms.
