## Abstract **The cover picture shows** a chromophore of the Green Fluorescent Protein, which undergoes fast internal conversion by rotation causing the quenching of its fluorescence in solution. In contrast, the intact protein shows a high fluorescence quantum yield and there is still a need to un
