The development of a novel PC-based gravimetric autotitrator is described. A single electronic balance serves as the weight buret for the delivery of three different solutions. It is therefore possible to add titrand and titrant under automated contr

Observing ligand 1H NMR signals while conditions (e.g., analytical concentrations, pH) are changed in an aqueous metal–proton–ligand system is one of the most potent methods of elucidating the precise details of speciation in such systems. Typica

The /sup 1/H and /sup 13/C NMR spectra of glutathione in its free and La(III)-complexes forms have been analyzed. The vicinal coupling constants were used to gain rotamer populations by the Karplus approach. The data were compared with the results of

The 1H nuclear magnetic resonance spin-lattice and spin–spin relaxation rate enhancements induced by the gadolinium(III) ion were measured in solutions of glycine, alanine, and sodium lactate containing different amounts of Gd(III). The proton rela
