Lennard-Jones potential

[′len·ərd ′jōnz pə‚ten·chəl]
(physical chemistry)
A semiempirical approximation to the potential of the force between two molecules, given by v = (A / r 12) - (B / r 6), where r is the distance between the centers of the molecules, and A and B are constants.

In addition to the Lennard-Jones potential, there are three interactions which contribute to surface or interfacial formation, two for the two different like-particle attractions and one for unlike particle repulsion.

Eleven appendices are included containing topics such as the thermodynamic and the transport properties of saturated water and steam, examples of Lennard-Jones potential model constants for selected molecules, and properties of selected ideal gases at 1 atmosphere.
The maximum depth of the Lennard-Jones potential energy function, or the maximum energy of attraction when molecules reside at their equilibrium separation distance (i.
3]OH, [DELTA]B is negative based on the Lennard-Jones potential, but its magnitude decreases monotonically at higher temperature.
As a result, the interactions between the DPD particles are not directly based on a Lennard-Jones potential, but are typically subject to three types of forces, namely, conservative forces, dissipative forces, and a random force.
