TY - JOUR A1 - Mikhailyuk, Igor K. A1 - Lokstein, Heiko A1 - Razjivin, Andrei P. T1 - A method of spectral subband decomposition by simultaneous fitting the initial spectrum and a set of its derivatives N2 - An improved method for spectral subband decomposition based on simultaneous fitting of the initial spectrum and a set of its derivatives is introduced. Additionally, it procedure for finding an optimal smoothing filter to obtain undistorted derivatives IS Suggested. The proposed method is demonstrated with a model spectrum as well its with experimental absorption spectra of the photosynthetic antenna complexes, peridinin-chlorophyll a-protein (PCP) and the main light-harvesting complex of higher plants (LHC II).
