Infra-red absorption of the hydroxyl group in relation to inter- and intramolecular hydrogen bonds

Development of the AVEC model for associating mixtures using NMR spectroscopy

“…The hydrogen bonds in the H F polymer configurations are among the strongest type of hydrogen bond known, with the energy of bond formation approximately 24-28 kJ/mol (Pimentel and McClellan, 1960). The results of X-ray diffraction studies (Warren, 1933;Pierce and MacMillan, 1938;Harvey, 1938Harvey, , 1939Wertz and Kruh, 1967;Narten et al, 1978;Narten and Sandler, 1979;Narten, 1979) on t-butyl alcohol and ethanol, infrared studies by the matrix isolation technique on methanol (Fox and Martin, 1940;Van Thiel et al, 1957;Bourderon et al, 1972;Luck, 1976), and the determination of average degree of association from viscosity measurements for the primary alcohols-methanol, ethanol, 1-propanol, and 1-butanol (Ratkovics et al, 1974)-can also be explained in terms of chain formation. The bond strength of the alcohol complexes is slightly weaker than the H F bond strength and is approximately 12-16 kJ/mol.…”

Understanding benzyl alcohol aggregation by chiral modification: the pairing step

“…These symmetrical aggregates compete with unsymmetric complexes on the basis of OH• • • OH hydrogen bonds. This question of symmetry for dimers of B has already been discussed 80 years ago 15 based on solution phase IR measurements. The spectral distinction of these dimer structures in the present work profits from the combination of IR and Raman spectroscopy in supersonic jets, also exploiting the rule of mutual exclusion.…”

Infrared studies of association in eleven alcohols

“…The spli tting of the free hydroxyl absorption was noted by Fox and Martin [14], working with benzyl alcohol, and by Coggeshall [15], working with phenols. Fox and Martin [3] presented evidence, based on equilibrium constants, against a singlebridge type of dimer, but in their later work [14] while suggesting the possibility that the band at 2.765 J.!…”

“…Fox and Martin [3] presented evidence, based on equilibrium constants, against a singlebridge type of dimer, but in their later work [14] while suggesting the possibility that the band at 2.765 J.! results from the interaction of hydroxyl and phenyl groups, they also consider the possibility of single-bridge dimeI'.…”
