The thermodynamic properties of amorphous polymeric nytrogen are analyzed theoretically on the basis of a free-energy expansion. An approach allowing estimation of the Helmholtz free energy of the high-pressure disordered condensed phases of nitrogen is proposed. The approach is based on expansion of the excess entropy in interatomic correlations and is tested on existing Monte Carlo simulation data. Some specific problems arising on this path and their possible solutions are discussed.
