摘要

A novel method for the analysis of the decay dynamics of densely produced, excited and ionic states is proposed, which makes it possible to estimate the rate constants of unimolecular and bimolecular processes from a transient emission or absorption curve. This method is based on a convolved autoregressive model, which is a linear form with respect to unknown model parameters, even for bimolecular excited state annihilation and ion recombination processes, so that the computation time is much shorter than that of a conventional non-linear least-squares fitting technique. The method can be extended to the analysis of a bimolecular process during irradiation by excitation light, which cannot be achieved using conventional techniques.
