Lanthanoid chirality as a tool for assignment of f-f transitions. Tb³⁺ and Tm³⁺ diglycolate

Abstract

Although chiral studies have proved to be handy in the assignment of transitions in biological molecules, organic molecules and transition metal complexes, its potentiality for lanthanoid transition needs to be demonstrated. The paper explores the usefulness of CD studies in the assignment of lanthanoid transitions with two specific chiral single crystals-thulium diglycolate (Tm³⁺-DG) and terbium diglycolate (Tb³⁺-DG). It has been shown that chirality can distinguish ΔJ=0, ±1 transition from others. The need for studies under higher resolution has been pointed out.
