Abstract
A Monte Carlo study of the dielectric constant of the polar hard dumb-bell fluid as a function of elongation l * is presented. The dielectric constant is found to be a decreasing function of l *. The simulation methodology is discussed and various routes to the dielectric constant and simulation energy are investigated. The dipole-dipole contribution to the energy agrees well with the energy calculated by the Ewald summation technique whereas the energy calculated from site-site correlation functions does not.
