What will be an ideal response? Latrina May 29, 2016, 06:30:01 PM #1 Answer The fluorescence lifetime is inversely proportional to the concentration of the quenching species. As the quencher concentration increases, the fluorescence lifetime de-creases. The slope of the plot is the rate constant for quenching.
