Structural properties of liquid formamide

Computer simulations of liquid formamide were carried out by the Monte Carl o method at 298 and 348 K. The atom-atom spatial distribution functions, th e concentrations of closed H-bonded ring, the radial distributions function s of the geometric centers of the rings, and a number of other characterist ics of hydrogen-bonded systems were calculated. It was found that the open chains dominate over cyclic structures, which are prone to association and formation of structural heterogeneities. Characteristic types of molecular associates were determined.
