Abstract
Hyperfine coupling to A for a range of X2AO and X3AO radicals with one electron less than the closed-shell species are reported and discussed, where X is–O–, –OH, or–OA, and A is either metallic or nonmetalic. It is concluded that spin polarisation of the A–O σ-electrons provides the major source of spin-density on A, and that the extent of this polarisation depends strongly on the extent of p–s or d–s hybridisation for A, and weakly upon the ionic character of the ligands.Keywords
