# Theoretical model for the hydrogen bond

I am curious how, from the perspective of quantum chemistry, the hydrogen bond is modeled. In particular I am interested in using such a model to estimate the amount of energy released per $\ce{H2O}$ molecule, if say two of them approach each other e.g. in case of condensation. Any hint for precise literature would be great!

• I am confused by your question. What do you mean by the amount of energy released per H2O molecule? There are a lot of models you can use. One of the simplest would be to consider a water dimer or perhaps an HF dimer. – LordStryker May 20 '15 at 15:55
• It's modeled as any bond in quantum chemistry. Plenty of references for that. There are however other models that are slightly more parametrized. Are you interested in those? – tschoppi May 21 '15 at 22:48
• Hi! Well I am interested in all sorts of models. If you have references this would be great! – Hamurabi May 25 '15 at 10:28
