- Аннотация: In this paper, a procedure for obtaining undistorted high derivatives (up to the eighth order)of the optical absorption spectra of biomolecule pigments has been developed. To assess the effectiveness of the procedure, the theoretical spectra of bacteriochlorophyll a, chlorophyll a, spheroidene,and spheroidenone were simulated by fitting the experimental spectra using the differential evolutionalgorithm. The experimental spectra were also approximated using sets of Gaussians to calculate themodel absorption spectra. Theoretical and model spectra can be differentiated without smoothing(high-frequency noise filtering) to obtain high derivatives. Superimposition of the noise track onthe model spectra allows us to obtain test spectra similar to the experimental ones. Comparison ofthe high derivatives of the model spectra with those of the test spectra allows us to find the optimalparameters of the filter, the application of which leads to minimal differences between the highderivatives of the model and test spectra. For all four studied pigments, it was shown that smoothingthe experimental spectra with optimal filters makes it possible to obtain the eighth derivatives of theexperimental spectra, which were close to the eighth derivatives of their theoretical spectra.
