Abstract: | The intensities of the ΔM = ± 1 component of the 7fo→ 5D2 transition in D3 complexes containing the EuO9] cluster, and of other d-d or f-f transitions in D3 complexes with the yz- and xz-components of the electric quadrupole as the leading moment, are found to be dependent upon the polarizability anisotropy of the ligands. The expectation is supported by determinations of the single-crystal absorption intensities of Na3 Eu(diglycollate)3]·2NaClO4·6H2O and Eu(H2O)9] (C2H5SO4)3. |
