In a conjugated organic system, each carbon atom corresponds to a π* orbital that allows electrons to hop across the molecule.For a system with n carbon atoms, at the lowest energy state, there are n π* orbitals that are perfectly aligned and allow electrons to meander throughout the organic molecule, such as shown in Fig. 1.When energy is added to the
