The absorption and fluorescence spectra of SmCl3 have been studied at 4°K and the Zeeman effects of many lines obtained in a magnetic field of 35 100 G. The lower group of levels obtained chiefly from the fluorescence spectrum can be unambiguously identified as the multiplet components of the 6H and 6F levels. The situation for the higher levels is confused. The splitting into Stark components of many of the levels could be determined with their symmetry and magnetic properties.
