The theory of a previous paper is applied to the paramagnetic resonance of certain cobalt salts. The splitting of the orbital levels by the crystalline field is first investigated, and then the further splitting by the spin-orbit interaction. The g-values so derived are in good agreement with experiment. The magnitude of the hyperfine splitting is also in good agreement.
