Abstract:
A method for the decomposition of optical spectra into bands was proposed, which is based on simultaneous approximation of the initial spectrum and its derivatives. The bands of the standard (gaussian) form were used in the decomposition procedure. A method for the selection of the optimal smoothing filter was described. The efficiency of the proposed method was demonstrated on model and experimental absorption spectra. It was shown that this method makes it possible to determine the number of bands and its parameters more exactly than the standard approach based on the analysis of one derivative of one power.
