In _______ a Molecule's Excited State Decays as It Emits

Question

In _______ a molecule's excited state decays as it emits a photon.
A) Oxidation-reduction
B) Radiationless decay
C) Resonance energy transfer
D) Both A and C are correct
E) None of the above are correct

Accepted Answer

The process described is fluorescence or phosphorescence, not listed among the options. Oxidation-reduction involves electron transfer, radiationless decay involves energy dissipation without photon emission, and resonance energy transfer involves energy transfer between molecules without photon emission.
