Generation of Cd +1 in x-irradiated frozen aqueous solutions: Similar hydration shells for Cd +2 and Cd +1 species

Abstract

Cd +1 has been generated in frozen aqueous solution by X-irradiation at 4.2 and 77 K. No difference in the g-factors or isotropic hyperfine constant has been detected for the two irradiation temperatures in contrast to Ag° species. Although the isotropic coupling constant indicates that 30% of the unpaired electron spin density of Cd +1 is delocalized onto first solvation shell waters it appears that the equilibrium solvation environments for Cd +2 and Cd +1 are essentially the same.
