On the identifiability and distinguishability of first-order reaction systems by time-resolved fluorescence spectroscopy

Abstract

We have analyzed the problem of the identifiability and distinguishability of first-order or pseudo-first-order photophysical reactions by time-resolved fluorescence spectroscopy. The uniqueness of the parameters leading to the identifiability and distinguishability has been verified using deterministic methods of compartmental modeling. It has been shown under what conditions we can obtain species-associated spectra of a two-state, excited-state model of a photophysical reaction. A discussion of the uniqueness of the estimation of parameters for monomer-excimer and monomer-exciplex kinetics is presented. The sufficient conditions of identifiability and distinguishability of these kinetics are given. © 1992.
