Fine-tuning: The origin of the metal and ligand contributions to the emission of a Pr(III) complex (see figure) is investigated. Analysis of spectroscopic data reveals the excitation energy pathway, and the authors show that the emission is modified by molecular distortion, particularly by rotation of the phenyl groups in the ligand.
