EXAFS studies of structural changes in fragile glasses of zinc nitrate and nickel nitrate hydrates

The ionic structures of aqueous solutions of two sets of transition metal nitrates have been studied in the liquid and glass states by EXAFS spectroscopy. Experiments were carried out on Zn(NO 3) 2· xH 2O, with x=2, 6, 12 and Ni(NO)·9HO over the temperature range 30< T( K)
