The influence of surface coverage to the structural properties of 4-n-octyl-4 '-cyanobiphenyl (8CB) monolayer at the air/water interface was studied by full atomistic molecular dynamics simulations. These properties include density profiles, interface thickness, monolayer width, orientational order parameters, and atom-pair radial distribution functions. The calculated tilt angles of the cyanobiphenyl and alkyl parts are in fairly good agreement with the experiments. The simulation results exhibit the general trends in the previous experimental and simulation data.
