Q1:

Fluorescence occurs when

A a molecule returns to the electronic ground state from an excited triplet state by losing it's excess energy as a photon

B a molecule returns to the electronic ground state from an excited singlet state by losing it's excess energy as a photon

C a molecule lowers its vibrational energy by losing it's excess energy as a photon

D none of the above

ANS:B - a molecule returns to the electronic ground state from an excited singlet state by losing it's excess energy as a photon
