Forster Critical Distance

Go Forster Critical Distance = 0.0211*((Refractive Index of Medium)^(-4)*(Fluorescence Quantum Yield without FRET)*(Orientation Factor)*(Spectral Overlap Integral))^(1/6)

Efficiency of Energy Transfer using Rate of Energy Transfer

Go Efficiency of Energy Transfer = Rate of Energy Transfer/(Rate of Energy Transfer+Rate of Non radiative Transitions+Rate of Radiative Transitions)

Efficiency of Energy Transfer using Distances

Go Efficiency of Energy Transfer = 1/(1+(Donor to Acceptor Distance/Forster Critical Distance)^6)

Efficiency of Energy Transfer using Rate of Energy Transfer and Donor Lifetime

Go Efficiency of Energy Transfer = Rate of Energy Transfer/(1/Donor Lifetime with FRET)

Donor Lifetime using Rates of Transitions Formula

Donor Lifetime = 1/(Rate of Radiative Transitions+Rate of Non radiative Transitions)
