In this paper, rate parameters are extracted from fluorescene decay data in the framework of Feedback‐Type Kinetics ( k 8 < k 4 ). The exciplex dissociation ( k 4 ) and fluorescene decay rate constants ( k 8 ) have been obtained for the five following systems:For this task we have added to the straight line method of Ware which is valid in certain cases only at high perturber concentrations, a new but similar Taylor series method applicable at low concentrations. Thereafter, a safer and more general method of kinetic analysis based on a quasi‐linear χ 2 minimization procedure has been developed and applies to data in any range of concentration.
