A few aspects of intermolecular hydrogen bond vibrations
are discussed. The methods of assignment of AH· ·B stretching
and bending modes depend considerably on the physical state as
shown for some carboxylic acids, phenols and alcohols, nitrogen
bases, and acid salts. A number of hydrogen bond stretching frequencies
and force constants are given and their correlation with.
AH stretching frequencies is discussed. The role of AH· · B vibrations
in determining the breadth and the structure of the AH
stretching band is analysed. Finally, the behaviour of the v OH· · 0
Raman bands during the phase transition of crystals of squaric
acid and cesium dihydrogen phosphate is described.
