) With the rate of thermal transitions at sufficiently high energy levels defined, I move the focus to the transition from one configuration to another. The central postulate in this work is now, that in such an event no energy is transferred. I call this process an adiabatic transition event, e.g., electron tunneling would be such an adiabatic event. Such an adiabatic transition is notably different from the thermal transition as derived in Eq. 7: While the driving force for thermal transitions appears to be the difference to an equilibrium state, adiabatic transition events will balance the probability for an element to be found in either configuration 𝑣 ⃗ and I can write the rate for an adiabatic event in either direction with the adiabatic frequency 𝑓 𝑎𝑑 as in Eq. 7a. Through acknowledging that an adiabatic event as such does not lead to the emission or adsorption of photons, the energy level must stay unchanged and both configurations must belong to the same energy level.
