Concept explainers

Photochemistry
Photochemistry is the part of chemistry that studies the various mechanisms of reactions that are triggered by the presence of light energy. It also helps to study the changes involved in a molecule that can undergo the absorption of radiation.
Question

The fluorescence of a fluorophore is quenched in the presence of iodide ions.

(i) Would the fluorescence quantum yield in the presence of iodide be larger or smaller than the fluorescence quantum yield in the absence of iodide? Explain your answer.

 

(ii) Would the fluorescence lifetime of the fluorophore in the presence of iodide be longer or shorter than the lifetime in the absence of iodide? Explain your answer.
