Abstract

The characterization of molecular structures around trivalent lanthanide ions(Ln³⁺) is essential for the understanding of biological functions for rare-earth ions as well as for other metal complexes. Conventional x-ray, nuclear magnetic resonance, and fluorescence lifetime measurement are falling short on one hand or the other to provide useful information for Ln³⁺ local structures. In this work, we report a powerful spectroscopic technique, the cooperative vibronic spectroscopy (CVS), to determine the molecular structures for Ln³⁺ compounds.
