The formation of borate esters of various mono-and di-saccharides in aqueous solution was studied by "B and 13C NMR spectroscopy. Association constants K(B-L) at a carbohydrate-borate molar ratio of 1: 1, pH 7, and 25°C were determined and compared with literature values obtained from potentiometry.

~H, '3(2, and ~s3W NMR spectroscopic methods were used for the structural characterization of the tungstate and molybdate complexes of volemitol (u-glycero-D-manno-heptitol) in aqueous solution. The major species (type E) are a pair of isomeric complexes formed at the arabino site in reversed orien
