摘要

The parameters of stretching vibrations nu(OH) (frequencies and integral intensities) have been calculated from IR spectra of a large number of H-complexes of 1,1 -diphenylethanol [(C6H5)(2)(CH3)OH] with solvents of various proton accepting strength which were not regularly reported. The data has been used to estimate the formation enthalpies of H-complexes and the proton-donor action of the mentioned alcohol. Also, correlations between those spectral characteristics have been investigated. The H-bonds in 1,1-diphenylethanol (DPE) have been investigated depending on concentrations in CCl4 and temperature by means of infrared (IR) absorption spectra measurments. It has been found that the hydrogen bonds of the crystalline DPE are formed in the manner of cyclic tetramer, while in solutions with the concentration 0.5 mol/l, cyclic dimers are formed, which in higher concentrations change into cyclic tetramers.
