The thermodynamical properties (equilibrium constants K, association enthalpies -ΔH, and association entropies -ΔS) and selected spectroscopic parameters (ΔνOH/νOH and ΔνOD/νOD of the associate band) of hydrogen bonded systems, formed by tert

The association between tertiary amines and some alcohols has been investigated by means of IR spectroscopy in the temperature range + 50°C to −26°C. Toluene was used as a solvent. The wave number difference of free and associated OH bands Δν O

The title compound (I) has been synthesized for the first time. Their spectra of the pure enantiomer and the racemic mixture (both dissolved in CCl4 to an association allowing concentration) are different from each other in characteristic features. T

The hydrogen bond between several alcohols, in particular benzyl alcohol and isopropanol, as donors, and a number of tertiary phosphines, as well as a smaller number of tertiary arsines, as acceptors was investigated by means of ir spectroscopy in th

The heteroassociation of three optically active alcohols and both enantiomers of two sulphoxides was investigated by means of IR spectroscopy. The equilibrium constants calculated using the intensity of the bands of the free OH groups show remarkable

The infrared spectral properties of deuterium bonds have been investigated in systems formed by tertiary aliphatic phosphines and benzyl alcohol-OD and/or isopropanol-OD in toluene as a solvent. The results are to be compared with those obtained in a
