New Interpretation

We give a new interpretation of Resonance Assisted Hydrogen Bonds (RAHBs) in which RAHB formation leads to an overall electron localization excluding covalency as the main source of stabilization. The most relevant contributions to the RAHB energetics are electrostatics, polarization and charge transfer.
