Structural physicochemistry of polysaccharide molecules. Vibrational spectra and structure of water soluble cellulose and starch ethers

For the first time, complex study of the structure of practically important water soluble derivatives of cellulose and starch (carboxy methyl, hydroxy ethyl ethers) with the use of coupled calculations of conformations and vibrational spectra, FTIR and Raman spectroscopy, mathematical treatment of spectral curves (deconvolution, numerical differentiation) has been performed. It is shown that such a complex approach is very promising in thin-structural analysis of these complicated polymer objects. q 2004 Elsevier B.V. All rights reserved.
