An empirical formula relating directly H⃛O interatomic distance to H⃛O interaction energy is used to estimate this energy in intramolecular O—H⃛O hydrogen bonds calculated for systems of known precise geometry. The values obtained were correlated with spectroscopic characteristics of the H-bond (Δv for OH bands in IR spectra and NMR chemical shifts, δ, for protons) and CNDO and INDO estimations of H-bond energy. The regressions obtained had good or very good correlation coefficients.
