## Förster cycle

https://doi.org/10.1351/goldbook.F02487
An indirect method of determination of @E02257@ equilibria, such as $$\text{p}K^{\text{*,a}}$$ values, based on @G02704@ thermodynamics and electronic transition energies. This cycle considers only the difference in molar @E02141@ change ($$\Delta \Delta H$$) of reaction of ground and excited states, neglecting the difference in molar @E02149@ change of reaction of those states ($$\Delta \Delta S$$).
