We point out the importance of the incidence energy of D{sub 2} to account for the nonmonotonic behavior of the adsorption probability of D{sub 2}/Cu(111) as a function of its initial rotational state. We then show that a very prominent initial cooling, a mild heating, and then a final cooling of the rotational temperature with respect to the surface temperature, for increasing rotational energies, should be observed for the desorption of D{sub 2} from Cu(111). We finally show that the desorption results could be consistently connected with the adsorption probability data. {copyright} {ital 1997} {ital The American Physical Society}
