The plot above show data recorded for three different experiments. In each case the fuorescent intensity of the system was studied in the abserce of quencher and in the presence of fincreasing concentration of quencher and the data used to generale the above plots: (a) What type(s) of quenching is/are consistent with each of the above plots (blue, grech, yellow)? Explain your reasoning fully. (b) Give examples of systems from the ifterature that show this type of quenching and brielly explain the system chosen. fuorescence iffetime of the fluorophore in absence of quencher is 4 ns, calculate the value of the quenching rate constant (ke.
