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 ...
