It is the key to explaining the mechanisms for superconductivity, electronic transport, etc. The EPC matrix describes the coupling of the electronic eigenstates of the studied system under the perturbation of phonons. …This interaction is called the "electronic coupling" between the orbitals and has units of energy. In the Hückel approximation this energy is the same for all carbon p-orbitals that are adjacent to on another and is called β. Non- Adjacent p orbitals do not interact. For atoms that are not adjacent to one another β is taken to be zero. When it comes to couples therapy, the Gottman Method has gained significant recognition for its effectiveness in helping couples build stronger and healthier relationships. Developed by Drs.Understanding the transport mechanisms of electronic excitations in molecular systems is the basis for their application in light harvesting and opto-electronic devices.
