Fluorescence intensity equation
WebJan 30, 2024 · The fluorescence intensity, IF is proportional to the amount of light absorbed and the fluorescence quantum yield, Φ If = kIoϕ[1 − … WebThe fluorescence transient, plotted on a logarithmic time scale, typically included the following phases: O to J, J to I, and I to P. Overall, F 0 represented the so-called “open” (O) state of the OJIP transient, and was the fluorescence intensity when all PSII reaction centers (RCs) were open.
