title: A method of spectral subband decomposition by simultaneous fitting the initial spectrum and a set of its derivatives.
abstract: An improved method for spectral subband decomposition based on simultaneous fitting of the initial spectrum and a set of its derivatives is introduced. Additionally, a procedure for finding an optimal smoothing filter to obtain undistorted derivatives is suggested. The proposed method is demonstrated with a model spectrum as well as 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).
