Abstract

The structural characterization of five oligomers from the carrageenan family and three oligomers of agarose, has been the aim of the present work. The compounds were chosen so as to study principally the effect of the substitution by a sulphate group on the two main vibrations due to the two glycosidic linkages (the (alpha) 1,3 and the (beta) -1,4). The C-O stretching modes of the two quoted glycosidic linkages have previously been identified in the spectral region between 1120 and 1160 cm^-1, whereas the C-O-C bending mode has been demonstrated to occur at about 730 cm^-1.
