Paper Abstract

The complex chains of hydrogen bonds of (Beta) -L-arabinose (I), methyl (alpha) -D- glucopyranoside (II) and di-(Beta) -D-fructopyranose 1,2':2,1'-dianhydride (III) in the crystalline state have been studied at variable low temperature. In addition to the increase of information showing up in the overall region upon cooling, the effect on intensity, bandshape and bandmaximum has also been studied. Most surprising is the contradictive behavior of the shift of the band maxima of methyl (alpha) -D-glucopyranoside, for which an increase is observed for the 'free' OH group, while H-bonds absorbing at lower wave-numbers are red shifted. Deuterium exchange experiments show the presence of vibrational coupling in the crystal of II whereas this phenomenon is absent in III.
