The way I understand quantum mechanics is that you can use it to make quantum mechanical models. The model can then be used to explain effects we see in nature. Things that can be explained this way are the presence of energy levels in nuclei/atoms/vibration/rotation. It seems to stop there. No apparent energy levels are present when more than one molecule is present with the exception of crystals. The quantum mechanical explaination of forces that hold crystals together is not fundamentally different from explaining molecules with weak bonds.
For liquids and gases when there are no quanta, no fixed intermolecular bonds and translational energy has to be considered why not stick to the classical explanation (opposite charges attract and like charges repel)?
If the purpose of this page is to explain intermolecular interactions why all the modelling theory? As long as a model cannot describe something accurately it certainly doesn't explain anything. A page such as this should focus on simple systems I would suggest focussing on interaction between two helium atoms and/or two hydrogen molecules, for molecules with atoms carrying partial/induced charge quantum mechanics won't explain better than classical mechanics126.96.36.199 (talk) 23:15, 10 December 2009 (UTC)
This article needs a better name
This article has scope issues. It is not clear what this article is or should be about. This may be solved by a better name (and lead). But I suspect the problem may run deeper and that the article needs to be split into several different articles each with a clear scope. TimothyRias (talk) 10:06, 27 April 2010 (UTC)
