摘要：

We have determined the alignment of D-2(upsilon,J) desorbed from Cu(111). The measurements reveal a small preference for ''helicoptering'' motion that increases with increasing J. At low J, the alignments are much smaller than predicted by recent calculations. We believe that the anisotropic potential may scramble the alignment as the molecules leave the surface.
