STATIC DIELECTRIC-CONSTANT OF THE POLARIZABLE STOCKMAYER FLUID - COMPARISON OF THE LATTICE SUMMATION AND REACTION FIELD METHODS

The static dielectric constant of the polarizable Stockmayer fluid is computed through Molecular Dynamics simulations where long range elect rostatic interactions are computed either by reaction field or by latt ice summation method (Ladd expansion). The effects on the simulated di electric constant of the truncation of the Ladd expansion and of the c utoff distance in reaction field geometry have been explored for diffe rent values of the polarizability.
