The reaction field method is used in molecular simulations to simulate the effect of long range dipole-dipole interactions for simulations with periodic boundary conditions. Around each molecule there is a 'cavity' or sphere within which the Coulomb interactions are treated explicitly. Outside of this cavity the medium is assumed to have a uniform dielectric constant. The molecule induces polarization in this media which in turn creates a reaction field, sometimes called the Onsager r… granite rack for truck bedWebIn Onsager reaction field model, the solvent is considered as a continuous unstructured dielectric with a given dielectric constant surrounding a solute embedded in a spherical cavity.
