The Zeeman effect of the visible absorption spectrum of the monoclinic europium chloride was investigated at 77 deg K and was completely explained by a first approximation perturbation calculation. From the line displacements observed the place of the magnetic transition dipole was determined relative to the indicatrix. The g factors of the excited terms ⁵D₁ and ⁵D₂are g = 1.43 plus or minus 0.04 and g = 1.44 plus or minus 0.05, respectively. The difference of the g factors in various europium salts is related to a noticeable intermixture of the states of free ions by crystal fields and magnetic fields. From the directional dependence of the Zeeman effect, it is concluded that the point symmetry C₂ of the Eu³⁺ ions in the lattice is D₆, in good approximation, with the hexagonal axis perpendicular to the monoclinic axis. The direction of the pseudohexagonal axis was not established.
