The principal diamagnetic susceptibility of azobenzene C12H10N2 with different stereostructures was measured, and their molecular values were deduced using the molecular-tensor relations. The measurements give evidence on their stereostructures and the shape of conjugation in the crystals. The results give acceptible information concerning the configuration and orientation of the molecules within these molecular crystals. Effect of the contribution of p-electrons on the magnetic anisotropy in crystals is also discussed.
