Abstract: The dissociation constants of DL-pantothcnate have been determined.Stability constants of the Nd(Ⅲ) pantothenate complexes in solution have been calculated from the oscillator strength of hypersensitive transition of Nd(Ⅲ) ion with change of ligand concentration. |
Keywords: hypersensitive transition oscillator strength stability constant |
