We have studied the fractal behavior in classical (MD) trajectories of liquid N2 and in continuous random walks using the "box counting method". For liquid N2, analysis of trajectories extending over a time of 60 ps gives a fractal dimen- sion D = 1.67, which is similar to previously results for liquid Ar. We find that for a continuous random walk with a com- parably small number of mean-free-path lengths the fractal dimension also falls below the theoretical value of two.
