The correlation between O—H stretching frequencies and hydrogen bond distances in a crystalline sugar monohydrate
TLDR
In this article, the Raman and infrared spectra of crystalline methyl 3,6-dideoxy-β-D-ribohexopyranoside monohydrate in the O-H stretching region have been studied at room temperature and lower temperatures.Abstract:
The Raman and infrared spectra of crystalline methyl 3,6-dideoxy-β-D-ribo-hexopyranoside monohydrate in the O—H stretching region have been studied at room temperature and lower temperatures. Four bands have been identified and correlated with the corresponding O … O distances of the four distinct hydrogen bonds obtained from X-ray data. The assignments were substantiated by a deuterium isotopic dilution study.read more

Hydrogen Bonding in Biological Structures
TL;DR: In this article, the van der Waals Radii cut-off criterion is used to define the strong and weak hydrogen-bond configurations, as well as the relationship between two-center and three-center hydrogen bonds.

An infrared spectroscopic study of the interactions of carbohydrates with dried proteins.

TL;DR: The ability of a given concentration of a carbohydrate to shift this band back toward the position noted with the hydrated protein coincided, at least in the extreme cases, with the capacity of that same level of carbohydrate to preserve the activity of rabbit skeletal muscle phosphofructokinase during freeze-drying.

Vibrational spectra of carbohydrates.
TL;DR: This chapter describes the various aspects of the vibrational spectra of carbohydrates, and the analysis of crystallographic results shows the important role played by anomeric center in the structure of sugars.

Second derivative F.t.-i.r. spectra of celluloses I and II and related mono- and oligo-saccharides
TL;DR: In this paper, the second derivatives F.t.r. bands in the OH and CH stretching regions of the spectra of celluloses I and II and of related mono- and oligo-saccharides are much sharper than those in normal absorption spectra.

X-ray and IR studies on crystal and molecular structure of 4-nitro-2,6-diphenylphenol. Stereochemistry of bifurcated OH⋯π hydrogen bonds
TL;DR: The first example of bifurcated inter-molecular hydrogen bonds was revealed by an X-ray structure analysis as mentioned in this paper, which was also supported by an observation based on the IR spectrum of the crystals.
