Monte-Carlo simulation of liquid N,N-dimethylformamide was performed.
The influence of electrostatic and van der Waals interactions on regul
arities of the mutual molecular arrangement was investigated. The spat
ial structure of liquid DMF is determined by the type of molecular pac
king and steric factors and is close to a random closely packed system
of soft spheres. The electrostatic interactions only affect the mutua
l orientation of the molecules.
