Question Solved1 Answer A certain molecule fluoresces at a wavelength of 400 nm with a half-life of 1.0 ns. It phosphoresces at 500 nm. If the ratio of the transition probabilities for stimulated emission for the S* → S to the T → S transitions if 1.0 × 105, what is the half-life of the phosphorescent state? Note: Please explain how you come up with the answer and write clearly so I can follow the solution.
