Which outcome occurs when a photon energy matches an excitation state's bandgap energy within fluorophore molecules?

💡 Explanation

Stokes shift occurs because incident photons boost electrons; this excites electrons from lower vibrational ground state to other energy levels, resulting shifts. Therefore, fluorescent emission occurs at longer wavelengths rather than direct reflection, because thermal relaxation lowers initial excitation.
