The homoassociative behaviour in molecules carrying dominant hydrogen bond donor and strong hydrogen bond acceptor functionalities has been investigated on the example of differently substituted 2-(X-pyridyl-)ethan-1-ols withXequals to 4, 3, and 2, a

Selected amino acid derivatives are investigated in order to obtain information about their intramolecular interaction, using infrared spectroscopy in the fundamental and overtone regions. A weak attractive interaction, responsible for the arrangemen

The self-association of selected O-deuteriated and normal (O-protonated) alcohols dissolved in CCl 4 was compared. The free OD band of the deuteriated alcohols decreases more strongly on increasing the OD alcohol concentration compared with the chang

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

Measurements of the diffusion behaviour of benzyl alcohol in toluene as a solvent were performed. The diffusion properties of the benzyl alcohol are unambigously changed by addition of several tertiary amines, which act as proton acceptors. The varia

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 heat of dilution to infinite dilution of solutions of trans (I) and cis 1-t-butylcyclohexan-4-ol (II) as well as t-butanol (III) and cis-para-menthanol-4 (IV) in CCl4 were investigated by ampoule calorimetry at 15° and 30° C. During this diluti

The association behaviour of four optically active secondary alcohols with chiral C atoms in the α-position was investigated by means of IR spectroscopy and calorimetry CCl 4 was used as a solvent. As compared to the racemic compounds, the correspon
