Interpretation Introduction

Interpretation:

The expression which shows the independence of collision quenching and direct relation to concentration by Fτ ratio should be determined.

Concept introduction:

The quantum efficiency of fluorescence is the ratio of quantum efficiency of fluorescence and the natural lifetime of the excited state in absence of quenching agent.

The magnetogyric ratio of 19F is 2.5177 x 108 T-1 s-1. Calculate the frequency of the nuclear transition in a field of 7.500 T.
An amino acid on the surface of an enzyme was labelled covalently with 1.5-I AEDANS and it is known that the active site contains a tryptophan residue. The fluorescence quantum yield of tryptophan decreased by 15 per cent due to quenching by 1.5-I AEDANS. What is the distance between the active site and the surface of the enzyme?
Consider the quenching of an organic fluorescent species with τ0 = 6.0 ns by a d-metal ion with kQ = 3.0 × 108 dm3 mol−1 s−1. Predict the concentration of quencher required to decrease the fluorescence intensity of the organic species to 50 per cent of the unquenched value.
