I was wondering about that ... I would imagine that the forces between molecular ions would not be bonds, but would still count as intramolecular if the two ions would make a molecule.
Also, in a aqueous medium apolar elements of a large molecule attract each other. That's very important for understanding, for instance, the behavior of large biological molecules.
It also occurred to me that atoms in a molecule that are not bonded to each other will experience forces due to each other. i.e. in CH4, the intramolecuar forces between the C and each H are bonds, but any forces between the H's are not.
