Dear all,
do you know a reference to a reasonable accurate Ar2 potential energy
curve that is valid for small bond lengths? I find only curves for
equilibrium and dissociation. Of course I could calculate it myself
but BSSE is non-trivial for small R. I will use the curve for
teaching, so it does not have to be super accurate, but should rather
have uniform quality over the whole curve.
Sincerely,
Ulf Ekstrom
