I. Benjamin et al., SCATTERING OF NE FROM THE LIQUID-VAPOR INTERFACE OF GLYCEROL - A MOLECULAR-DYNAMICS STUDY, The Journal of chemical physics, 100(9), 1994, pp. 6500-6507
A model potential for the scattering of Ne off liquid glycerol is deve
loped. The model is based on a nine-site description of glycerol which
takes into account torsional flexibility and hydrogen bonding. This m
odel is used to carry out molecular dynamics calculations of the scatt
ering as a function of collision energy. The results for the sticking
probability and energy transfer are in good agreement with experiments
. The model predicts a wide angular distribution of the scattered atom
s with a mild decrease in the energy transfer as a function of exit an
gle for a fixed incident angle. The model also provides insight into t
he importance of the corrugated nature of the surface and the types of
liquid modes that play a major role in the energy transfer process.
