13C Hyperfine splitting in the radical complex of bis(ethoxythiocarbonyl)sulfide and dimanganese decacarbonyl

A close examination of the ESR spectrum of a paramagnetic complex formed from bis(ethoxythiocarbonyl)sulfide and dimanganese decacarbonyl has revealed, for the first time in this type of radical adducts, 13-C hyperfine coupling in natural abundance from the carbonyl ligands.
