Left axis represents the energy and bottom axis represents time. Blue squiggly arrow represents a high energy photon that is absorbed by the molecule. Blue arrow represents the transition of the electron to a possible excited electronic state. Green arrow represents energy dissipation between vibrational states. Red arrow represents the transition of the molecule to a ground electronic state where the energy is dissipated through electromagnetic emission represented with the red squiggly arrow. If the molecule does not come back to the true ground state after electromagnetic emission decay, it can further decay through energy dissipation until ground state is reached. .. 37 Figure 19.
