The angular distribution of PF 3 molecules adsorbed on Ru(0 0 1) surface is studied with use of Monte Carlo simulation. The rotational motion of the molecules is treated as gears engaged to each other. The coverage dependence of the angular distribution of the molecules such as that observed by electron stimulated desorption ion angular distribution can be explained by considering the coupling between the lateral distribution of PF 3 molecules and their rotational motion.
