Abstract

The analysis of spectrum change in visible spectroscopy is a common aapproach in photobiology research. This analysis is made difficult bythe overlapping of spectral bands which is due not to lack of instrumental resolution but rather to intrinsic properties of the examined biological material. To minimize the overlap bands, an FT-IR spectroscopy method called Line Shape Optimized Maximum Entropy Linear Predictionhas been proposed. This method is based on the spectral deconvolution, maximum entropy and linear prediction methods (J.K. Kauppinen et al,Appl. Spectrosc., 45, 411, 1991). We present a model study which for the first time enables the use of the deconvolution, method and autoregression in visible spectroscopy By analyzing the phototransformation kinetics of pigment-protein complexes in etiolated barley leaves, we demonstrate the advantages of this new analytical approach compared to the methods used to date (D.G. Cameron et al., 41, 539, 1987; R.D.B. Fraser et al., Anal. Chem., 38, 1770, 1966).
