Figure 3. — The configuration coordinate diagram to describe events in olfaction is shown. Electron tunnelling from the donor |D〉 to acceptor |A〉 is facilitated by the excitation of an appropriate odorant phonon corresponding to The change in force as the electron transfers is characterized by the shift in energy, down the vertical axes E, and displacement, along the reaction coordinate Q, that is phonon assisted. The reaction coordinate describes the displacements of nuclear modes that entail the reaction pathway.
