A COMPARISON BETWEEN THE QUASI-CHEMICAL APPROXIMATION AND THE MONTE CARLO EOD FOR THE STUDY OF MONO~YER MODELS OF SOLVENT DIPOLES (original) (raw)

Abstract

The effect of a varying external electric field on a tw~dimension~ lattice of point dipoles with a relatively high number of orientaticns is examined both by a generalized version of the quasi-chemical approximation and by a Monte Carlo technique. Agreement between these two procedures is found to be excellent. Monte Carlo calculations in which a continuous uniform distribution of dipole orientations is generated by random numbers yield results in satisfactory agreement with those of a quasi-chemical approximation employing a sufficiently high number of discrete dipole orientations with a uniform density along all directions of three-dimensional space.
