| Charge-dipole interactions
| The potential energy now falls off as 1/r^2

| Dipole-dipole interactions
| Note that the potential energy between two dipoles falls off as 1/r^6
power.
| Dipole-dipole interactions are short-range interactions
|
| Dipole-induced dipole interactions

| Induced dipole-induced dipole interactions
| This instantaneous dipole can then induce a dipole in a neighboring

dependence.

| A commonly used analytical form that lumps together all

Could you explain an apparent inconsistency in you data Sue as you have
Coulomb at 1/d^2 and POINT CHARGE with POINT CHARGE 1/r. I thought
Coulumb was a point to point charge definition. ?

Maybe updates. The spuds, beans and onions are coming up nicely. Ooh
ah.{:-)
