This may be too subjective for this forum, but I'll take my chances.

For the purposes of a "quick and dirty" illustration of London forces, I'm looking for best practices and creative ideas. For something like dipole-diple attractions, there are some largely-agreed-upon conventions:

enter image description here

But for London forces, there is a shortage of good ways to illustrate them in notes or on the board. Personally, I have used these in the past:

enter image description here But there must be other, clearer, more clever means of illustrating London forces. I've searched the questions here on London forces but I don't see that this issue has been addressed.

EDIT: I'm interested in ways of showing modest organic molecules interacting via London forces. The vast majority of illustrations found via Googling show only rather small molecules or atoms. It seems to me that the illustration ought to convey the notion of the molecules at close range (or snuggling, as I generally tell students), since London forces are impossible otherwise.

  • $\begingroup$ @user34388 If you are thinking about the diagram from Purdue, don't you think it is wrong to distort the electron cloud? Electrons moving w/i their orbital don't control the probability distribution of the orbital do they? That style also doesn't scale to even slightly larger molecules in a practical way. $\endgroup$ Commented Sep 16, 2016 at 14:48
  • $\begingroup$ Then use a diagram which does not distort the cloud? What you drew is quite good. $\endgroup$
