Abstract
ATTENTION has recently been directed by Gorter1 to the existence of a splitting of the energy-levels of paramagnetic salts due to the coupling between the electronic and nuclear magnetic moments. The level separation, which is of the order of 0·1 cm.â1, is seen in the hyperfine structure of the optical line spectrum. Now such a splitting, ought also to lead to a Schottky specific heat anomaly at temperatures of the order of 0·1° K., that is, some 104 times higher than in salts the paramagnetism of which is due only to the nuclei.
