“…Many details of carbohydrate vibrational spectra and correlated structures have been given in the literature. Examples of these refer to positions of various types of bands of D-glucopyranose derivatives, [1][2][3][4][5] D-or L-aldopyranoses and their derivatives, 1,3,6,7 and ribose derivatives. 8 -10 However, spectrumstructure correlations regarding intramolecular hydrogen bonds of carbohydrates in aqueous solutions are still lacking.…”

Vibrational coupling as diagnostic for intramolecular hydrogen bonds of carbohydrates in aqueous solution

The coupling of nuC-O and deltaO-D vibrations in the 1200-900 cm(-1) IR range leads to band shifting in opposite directions, which provides information on intramolecular hydrogen bonding of carbohydrates in aqueous solution. The aqueous solution IR spectra of 2-acetamide-1,6-anhydro-2-deoxy-D-glucopyranose and cis-1,2-cyclopentanediol and tetrahydrofuran-ethanol mixtures are reported. Frequency upshifting upon deuteration is observed for the nuC-O bands of both a hydrogen bond acceptor and donor in ether-hydroxyl and hydroxyl-hydroxyl contacts. The 1200-900 cm(-1) range can be used to reveal the presence of intramolecular hydrogen bonds in aqueous carbohydrates, unlike the OH stretching region, which cannot be used in this sense due to carbohydrate band masking by the strong nuOH IR absorption of water.

“…[8,9] Some changes of the CH 2 stretching vibrations have been observed when going from the liquid state to the intercalated form of THP. During the fixation of the intercalated molecules in the interlayer space, the asymmetric CH 2 stretching vibrations at 2936 and 2840 cm -1 split into several bands and a new doublet shifted to 3002 and 2993 cm -1 appears in the infrared spectrum of the intercalated THP (see Figure 3).…”

“…Going from the liquid to the intercalated state of THP a change of the scissoring (several bands from 1380 to 1470 cm -1 ), wagging (at about 1350 cm -1 ), twisting (at about 1250 cm -1 ), and rocking (at about 1150 cm -1 ) vibrations of the CH 2 group have been observed in the infrared spectrum of the intercalate (see Figure 4). [8,9] The band of the asymmetric C-O-C ring vibrations at about 1090 cm -1 is overlapped by PO 4 vibrations of vanadyl phosphate in the infrared spectrum. The position of the deformation ring vibration is shifted from 817 to 813 cm -1 in the infrared spectrum.…”

Thermal Behavior of Tetrahydropyran‐Intercalated VOPO₄: Structural and Dynamics Study

et al. 2007

Keywords: Intercalations / NMR spectroscopy / IR spectroscopy / Thermal behavior / Quantum chemical calculationsThe thermal behavior of tetrahydropyran-(THP-)intercalated VOPO 4 was probed by an extensive combination of experimental methods (XRD, DSC, FTIR, solid-state NMR) and quantum chemical calculations. Two temperature-induced transitions were detected and all polymorphs exhibit a high degree of molecular order and tight packing of THP in VOPO 4 . The first reversible thermal transition at around 100°C was attributed to boat/chair conformation changes of the THP molecules. Most probably, a low-temperature boat conformation of the guest molecules present in the interlayer space of VOPO 4 changes to a high-temperature chair confor-

Nous les attribuons au cycle pyrannosique de la cellulose par comparaison avec ce que l'on sait sur le 03B2-D-glucopyrannose, la cellobiose et la cellulose (tableau 1) [3][4] Les autres bandes (tableau II) ont été identifiées avec certitude, sauf en ce qui concerne la région comprise entre 1 000 et 1 200 cm-1. Trois hypothèses ont été formulées à son sujet, tout particulièrement en ce qui concerne la bande à 1 162 cm-1.…”

2014 La spectrométrie d'absorption infrarouge constitue ici une technique d'investigation des dommages créés par l'irradiation d'un détecteur solide de traces. L'irradiation est obtenue par des ions Kr8+ (1 MeV/nucléon). Les détecteurs sont des films de triacétate de cellulose mis au point au laboratoire. Nous montrons que les trois types de liaison C2014O que contient la molécule de triacétate de cellulose sont affectés par l'irradiation pour des flux d'ions différents suivant le type de liaison et variant par pas de 2 x 1012 ions/cm2. Abstract. 2014 Infrared Spectroscopy was used to study radiation damage effects on Solid State Track Detectors bombarded with Kr8+ ions (1 MeV/nucleon). Cellulose triacetate films, produced by a method developed in our Laboratory were used. It is shown that the three kinds of C2014O bonds contained in the cellulose triacetate molecule are affected, according to their types, by different irradiation fluences, the latter varying by steps of 2 x 1012 ions/cm 2.
