Theoretical analysis of coverage dependent rotational hindrance of PF3 adsorbed on Ru(001)

H.Kaji, K.Kakitani, Y.Yagi, A.Yoshimori

Distribution of the azimuthal orientation of PF3 molecules adsorbed on Ru(001) measured by ESDIAD shows interesting temperature and coverage dependences. It is interpreted in this analysis as due to the short range order in the locative distribution of the PF3 molecules. Monte Carlo simulations are performed to obtain the temperature and coverage-dependent distribution of the adsorbed molecules. The distribution of the azimuthal orientation of the molecule is discussed on the basis of the obtained locative distribution of the molecules by using simple models for rotational hindrance to be compared with the experimental results.
