摘要：

We have performed molecular dynamics (MD) simulations along a low-temperature isotherm for a system of strongly dipolar elongated molecules. The model molecules are found to associate to form well defined chains; this association is induced by the dipolar interaction. The order parameters, the polarization and the average number of molecules in a chain have been calculated for a range of densities.
