Rotational and Spin-State Distributions: NO Thermally Desorbed from Ru(001).

Abstract

Rotational state distributions have been measured for the first time in molecules thermally desorbed from a metal single crystal. Laser excited fluorescence has been used to monitor, under ultra-high vacuum conditions, the desorption of NO from Ru(001). The population distribution for those states with less than 400/cm of rotational energy (including spin) can be represented by a single Boltzmann factor, T(rot)=235 + or - 35K, significantly lower than the surface temperature at the desorption maximum, T(S) = 455 + or - 20K.
