✦ Synopsis

The purpose of this paper is to examine a simple polar-polarizable model for liquid ammonia. Theoretical values of the mean molecular dipole moment and the static dielectric constant are reported for temperatures ranging from -70°C to 35°C. The theoretical results are obtained by solving the self-consistent mean field (SCMF) equations within the reference hypemetted-chain (RHNC) approximation. It is shown that molecular polarizability has a large influence upon the properties of this system. The theoretical dielectric constants are in fair agreement with experiment over the temperature range considered.
