For the Lennard-Jones interatomic potential, the portion of the graph between r = sigma and r = equilibrium has a negative potential energy (attraction) and a negative force (repulsion). I am trying to reconcile these two.

A specific model for the atom-atom potential was constructed by John Lennard-Jones (1894-1954). It is therefore known as the Lennard-Jones potential and it is a reasonable approximation for the regions that atoms typically explore in biological systems.

Graphing Lennard-Jones interaction. So we have to graph the Lennard-Jones interaction potential function U (R)=B [ ( (σ/R) 12) - ( (σ/R) 6) with R being the interatomic distance and B and σ as constants. the homework says we need to graph it using excel or another graphing program. it also says you want to plot U/B versus R/σ so you don't

I'd appreciate any help and advice.

According to the Lennard-Jones potential, any value of r greater than σ should yield a negative bonding potential and any value of r smaller than σ should yield a positive bonding potential. Lennard-Jones Potential and First Two Derivatives to save your graphs! New Blank Graph.
