Hydrogen bonding in amides

Electrostatic interaction and resonance

Proceedings of the Indian Academy of Sciences - Section A Aims and scope Submit manuscript

VI. Summary

The shift in the N-H stretching frequency in the infra-red spectra of amides, due to intermolecular associations, calculated on the basis that the hydrogen bonding is essentially an electrostatic interaction and that the ionic character of the bond diminishes on hydrogen bonding. The calculated and the observed values of the frequencies agree only when the two possible resonance structures in amides are taken into consideration for calculations.
