It is shown that, in order to describe and understand the trends found experimentally for the variation of the H2 sticking probability with crystal face on Cu and Ni surfaces, the dynamics of all six molecular degrees of freedom must be included. The effective-medium theory is used to estimate the multidimensional interaction potential and the dynamics is studied using two- and six-dimensional quantum and classical simulations.
