We demonstrate that the minimum information method (MIM) is a useful tool in deconvolving multiexponential fluorescence spectra (Landl, G., Langthaler, T., Engl, H. W., and Kauffmann, H. F., J. Comput. Phys. 95, 1 (1991).). We sketch some theory and two simulated examples. The method is a straightforward normalized least-squares fit with regularization by Prussian-Helmet smoothing.
