We report rotationally state-resolved measurements of the average
steric orientation of 
molecules desorbing from a Cu(111)
surface. The desorbing flux of molecules is probed by
laser-induced fluorescence with linearly polarized tunable vacuum
ultraviolet radiation in the 
. Molecules desorbing
in the vibrational ground state show for all rotational states
measured 
a quadrupole alignment factor, 
,
compatible with a spatially isotropic distribution. A strong
azimuthal, polar, and lateral corrugation of the dissociative
interaction potential can cause this behavior.
