In absorption saturation measurements the reaction quantum yield can be calculated from the dependence of the probe beam transmission on the energy of the exciting pulses provided that the probing is performed at wavelengths in the photoproduct absorption band and that excitation is at the absorption wavelengths of the substrate. This approach was used to determine the reaction quantum yields of light-induced intramolecular proton transfer reactions.
