Unstable intermediates. Part XLIV. Solvated electrons: further studies of solutions of the alkali metals, including sodium in amines, by use of electron spin resonance and optical spectroscopy

Abstract

The electron spin resonance absorption of the solvated sodium atom in ammonia–ethylamine mixtures is reported. The atomic characters of the other solvated alkali atoms are compared with that of sodium. The dependence of line-width upon alkali metal nuclear spin configuration is interpreted in terms of an equilibrium between two species, one having a very small hyperfine coupling and the other having a coupling close to the atomic value. Concentration-broadening of the central singlet is interpreted in terms of interactions with the diamagnetic species which account for the majority of the dissolved metal.
