Ultraviolet spectra of anhydrous metal nitrates

Abstract

Ultraviolet spectra are reported for solutions of anhydrous nitrates of sodium, beryllium, magnesium, zinc, cadmium, mercury(II), manganese(II), cobalt(II), nickel(II), copper(II), and silver(I) in water and in several organic liquids. The π*â†�n band of the nitrate ion is shifted to lower energy when this group acts as a ligand. Diffuse-reflectance spectra of some complexes of metal nitrates with water and with dimethyl sulphoxide are reported.
