Paper Abstract

The determination of life times from experimental data of luminescence decay curves (being represented as a sum of a some number of the exponent function with unknown weight factors and often with unknown error of measurement), was and now remains important for time resolved spectroscopy of complicated bio-organic molecules and complexes. Standard approximation procedures (the method of least squares, Laplace transform) used for this purpose does not always permit us to receive the unequivocal 'spectrum' of exponent. The recently proposed maximum entropy method requires the additional data about anisotropy of molecule polarizability and its relaxation, the energy population of investigated molecules on various degrees of freedom, etc. Therefore development of alternate techniques of expansion of the experimental decay curve from exponential sum is important.
