Question

The figure below shows the relationship between absorption and fluorescence spectra. Which of the following statements are true? Check all that apply. Fluorescence is shifted to shorter wavelengths with respect to absorption. Internal conversion results in fluorescence spectra originating from the lowest vibrational state of S1. Internal conversion to the ground vibrational state of S1 is not generally fast in comparison with fluorescence to S0. If fluorescence were fast with respect to internal conversion, the fluorescence and absorption spectra would lie in the same frequency range.
