self-diffusion coefficients and structural properties of N-methylformamide were studied by molecular dynamics simulation over wide ranges of temperature and pressure. The simulation results agreed well with the experiment of diffusion
and the average relative deviation was 7.3%
which suggested that one can use the simulation method as a powerful tool to obtain self-diffusion coefficients over wide ranges of temperature and pressure
under which it was rather difficult for experiments. In N-methylformamide
oxygen and amino hydrogen formed strong hydrogen bond
while oxygen and carbonyl hydrogen formed weak interaction. The temperature effects were more pronounced than the pressure effects on self-diffusion coefficients and radial distribution functions.
