Abstract : The tangential velocity distribution of ground state NO (J' = 9 1/2, E(rot)=165/cm) thermally desorbed from Ru(001) under ultra-high vacuum conditions was measured by laser excited fluorescence Doppler spectroscopy. The measured Doppler profile was Gaussian in nature, characterized by a temperature T = 235 + or - 45 K significantly lower than the surface temperature at the desorption peak of 455 K.
