How to Evaluate Anisotropy Decay Behavior?

Anisotropy Decay Behavior evaluator uses Anisotropy Decay = (Parallel Transient-Perpendicular Transient)/(Parallel Transient+(2*Perpendicular Transient)) to evaluate the Anisotropy Decay, The Anisotropy Decay Behavior formula is defined as time-resolved anisotropy measurement where a sample is excited, by linearly polarized light, and the anisotropy (or polarization) decay of the resulting emission is evaluated, by observing the fluorescence decay at polarizations parallel and perpendicular to the excitation. Anisotropy Decay is denoted by R symbol.
