Circular dichroism of gadolinium(III) tris(oxydiacetate) single crystal

Abstract

The electronic absorption and circular dichroism spectra of optically active single crystals of Gd^III tris(oxydiacetate) are reported. The relative values of the ratio of rotational strength (R_K) to square root of dipole strength (D_K) are compared with relative values of the gross magnetic dipole moments of the ƒ→ƒ transitions. The validity of some “soft” selection rules for optical activity, e.g.ΔJ, ΔL⩽ 1, are considered.
