A theoretical analysis of MCD and absorption is made for transitions involving J = 0 and J = 1 states using a general field model. Magnetic dipole, electric dipole, and electric quadrupole contributions are considered. The ratio of absorption intensity to first moment of MCD is shown to depend on the g-factor and the fractional contribution of the various types of transition moments. The theory is applied to the 7F0 → 5D0 and anhydrous ethanol and leads to the conclusion that the europium ion has low symmetry in both solvents. The theory is also applied to the 7F1 → 5D0 transition of EuCl3 in water.
