Solvation spectra. Part 14.—Ultra-violet spectral studies of silver iodide complex ions

Abstract

Ultra-violet spectra of solutions of silver iodide complex anions and cations in a range of solvents and of certain solid complexes have been measured. Spectra have been assigned to the anions AgI^–₂ and Ag₄I^2–₆ with some confidence and to several others tentatively. The low-energy band found for solid silver iodide is not detected in any of the complex ions. This helps to confirm the view that this band is a property of the particular crystal lattice.
