The L-J potential is of the form The function I'm trying to plot is the derivative of the Lennard-Jones potential equation wirth respect to distance, thus it simulates the van der Waals forces. The function itself and the plot of the function is given in the attachments at my first entry. 2018-05-18 · The Lennard-Jones potential is commonly used to represent hard-sphere repulsion and van der Waals attraction, but it is not easily integrated into continuum mean- eld equations for the electrical double layer. Here, a double Yukawa potential is t to the Lennard-Jones interaction, and the double When using Lennard-Jones potentials in simulations, the most appropriate system of units adopts σ, mand εas units of length, mass and energy, respectively, and implies making the replacements: r → rσ E → Eε t → tσ(m/ε)1/2.
