title: Some Brief Notes on Theoretical and Experimental Investigations of Intramolecular Hydrogen Bonding.
abstract: A review of selected literature data related to intramolecular hydrogen bonding inortho-hydroxyaryl Schiff bases,ortho-hydroxyaryl ketones,ortho-hydroxyaryl amides, proton sponges andortho-hydroxyaryl Mannich bases is presented. The paper reports on the application of experimental spectroscopic measurements (IR and NMR) and quantum-mechanical calculations for investigations of the proton transfer processes, the potential energy curves, tautomeric equilibrium, aromaticity etc. Finally, the equilibrium between the intra- and inter-molecular hydrogen bonds in amides is discussed.
