Optically active co-ordination compounds. Part XXVI. Determination of the optical purity of cobalt complexes by the method of isotope dilution

Abstract

The method of isotope dilution has been used to determine the optical purities of samples of partially resolved salicylatobis(ethylenediamine)cobalt(III) nitrate and of oxalatobis(ethylenediamine)cobalt(III) chloride and hence to obtain values of ΔIµmax for peaks in the circular dichroism spectra of the fully resolved complex ions.
