The influence of universal and specific interactions on structural properties of liquid formamide

Monte Carlo simulation of the structure of liquid formamide at 298 K was ca rried out. Intermolecular interactions were calculated using, five differen t potentials. No essential changes in the spatial structure and topological properties of the network of hydrogen bonds of liquid formamide occur upon varying the electrostatic intermolecular interactions, strength of H-bonds , and temperature. Fragments of crystal structure are partly retained in li quid formamide. It was found that the network of H-bonds is structurally in homogeneous and contains long-lived associates of closed cycles of H-bonds as well as tree-like and chain-like structures. The energy, topological, an d statistical characteristics of closed cycles of H-bonds were determined.
