Infrared Spectroscopy of the Hydrogen Bond as a Method for the Investigation of Intramolecular Interactions

Infrared tpectrotcoplc data on hydrogen-bonded complexes incorporating the main classes of organic and organoelemental electron donors and electron acceptors are examined and surveyed. The dependence of the parameter Δν (the frequency shift of the stretching vibration of the A–H bond in the infrared spectrum of the electron acceptor on formation of the hydrogen-bonded complex) on intramolecular interactions in the molecules of the species involved in the hydrogen bond is analysed. The use of this parameter in the investigation of weak electronic effects of substituents in the molecules of electron donors and electron acceptors involved in the formation of the hydrogen bond is considered. The bibliography includes 191 references.
