WebFeb 1, 2024 · In the case where the total absorbance is high, A A Δ λ > 3, the photokinetic factor (Eq. (4)) becomes a good approximation of the reverse total absorbance, F Δ λ (t) × A A Δ λ (t) = 1, since when A A Δ λ (t) becomes much larger than 1, (1 − 10 − A A Δ λ (t)) tends to 1. Henceforth, the modified rate-law (Eq. (5)) integrates into ... WebThe approach chosen to transform the axis of the radiation time into a new variable that includes the photokinetic factor proves that formal kinetics can be applied to thermal and photochemical reactions as well, and even allows the handling of solutions that cannot be homogenised or solid samples in which the concentration varies locally.
