[edit] Summary

Description	The figure explains the fluorescence phenomenon using energy level diagram. The left half shows the vibrational and electronic energy levels of an absorbing molecule. An electron in the lower energy level (ground energy level) absorb a laser photon and is transferred to an upper (excited) energy level. If this electron gives out a photon during the process of getting de-excited, then that photon is seen as a fluorescence signal.
