Figure 3.50. The partial quantum yields

As derived in Appendix 6.2.2, the partial quantum yields are found as... 

The partial quantum yields do not depend on irradiation intensity according to eq. (3.29). For this reason the same situation is valid for K-diagrams. The form of the K-diagrams is determined by eq. (3.40). The related constant x contains the ratio k, which varies with wavelength. For this reason the K-diagrams have to depend on the wavelength of the irradiation source. 

Section 2.1.2 demonstrated that the quantum yields depend on the concentration of the reactants in a characteristic way (in general the true differential and the partial quantum yields respectively). Iliis correlation can be used for kinetic analysis. 

They are in good agreement with the measured absorption independence on time. The constants are used to calculate the partial quantum yields which amount to... 

Usually the intermediate s absorption coefficient is not known. Therefore apart from (p (using eq. (S. 145)) no further information can be gained. Accordingly the evaluation of the second slope in the intensity time diagrams only allows an approximation of the third partial quantum yield for known Cg. In any case, however, the two slopes have to differ by at least one... 

This latter equation is a matrix equation like eq. (4.6). Multi-linear regression allows the determination of the molar absorbance coefficients for any wavelengths which have been measured. The calculated absorption coefficients can be used to allow the determination of the partial quantum yields, (pi and absorption coefficients into the parameters p, W, and R respectively [177,178,185].
