Abstract
This Chapter is about molecules. A molecule is a collection of nuclei Z k , Z l ,...at rest (in the Born-Oppenheimer approximation) in a sea of fast-moving electrons. The nuclei can be identified and thus provide convenient reference marks. Each nucleus found in a molecule, say, Z k , can be viewed as the nucleus of a ‘giant atom’ extending over the entire molecule: Z k is surrounded by charges, just like in an ordinary atom, with the difference that motionless positive point charges are now part of its environment. Of course, the electronic content is still described by its stationary density.
