The molecular Zeeman effect in diamagnetic molecules and the determination of molecular magnetic moments (gvalues), magnetic susceptibilities, and molecular quadrupole moments

The experimental and theoretical literature on the molecular Zeeman effect is surveyed. The observation of the linear (H) and quadratic (H 2) Zeeman effect leads to a direct determination of the molecular g values, magnetic susceptibility anisotropies and molecular quadrupole moments. The recent results are discussed and the available molecular g values, magnetic susceptibility anisotropies, and molecular quadrupole moments are tabulated.
