Potential formula Confusion

[reshnashrestha]

The ion-ion potential in K.Michaelian paper is: and the one found in the Compphys minmax is:

and in the paper, the potential formula is referenced to: For this homework, which formula should we follow?

[sharmistharanit]

Both formulas are the same. In comphysminmax, i,j represent Na and cl ions.

[sharmistharanit]

The above equation represents the positive and negative ions interaction.

[sharmistharanit]

On the other hand, this equation represents the interaction between either positive-positive ions or negative-negative ions. I believe so.

[sharmistharanit]

This equation is the combination of all interactions. (positive and negative ions interaction + positive-positive ions interaction and negative-negative ions interaction).

Hope this helps.

@sharmistharanit Lucid explanation..

[Mosaddeq107]

Both formulas are the same. In comphysminmax, i,j represent Na and cl ions.

How did you find this?
