Interactions between oxovanadium (IV), glycylvaline and imidazoles: An aqueous potentiometric and spectroscopic study

Speciation has been determined in aqueous oxovanadium, glycylvaline and imidazoles at 25 plus-minus 1C and mu = 0.1M NaClO4 using a combination of potentiometry, and visible and EPR spectroscopy. Results of potentiometric and spectroscopic methods are consistent. Calculations of stability constants have been made using the SCOGS computer program.
