Abstract
Electron transport is considered in the metallic range of metal-ammonia solutions; the scattering centers are (i) ions and ammonia dipoles weakly bound in solvated ion complexes, and (ii) free ammonia dipoles. They form a binary liquid mixture, but only one of the three possible partial structure factors is required. From the orientational degrees of freedom of the dipoles, it can be shown that much of the scattering is incoherent. This, combined with the observation that solvated ions are relatively weak scatterers, accounts in large measure for the high conductivities measured in metal-ammonia solutions.
