## Abstract DOSY NMR spectroscopy can be a fast and easy method to establish qualitatively the relative order of magnitude of the exchange rates of systems in slow exchange in chemical shift. By measuring a series of DOSY spectra of a twoβsite exchange system, where exchange occurs between sites wi

To fix toxic heavy-metal ions, plants synthesize the ligands (Ξ³-Glu-Cys) -Gly (PC ), whose simplest representative is the pentapeptide PC . The knowledge of the composition and stabilities of the cadmium complexes of PC allow a better understanding of biological processes like the one outlined.
As industrial applications for polymers and biopolymers have expanded in recent years, the limitations of traditional characterisation techniques have become apparent. Size exclusion chromatography is widely used to determine the molecular weight distribution of a polymer, but su β ers from a number
