The UV laser-induced desorption of CO from an epitaxial film of NiO(1 0 0) on Ni(1 0 0) yields a linear dependence of the desorption signal on the laser intensity with a cross-section of (8.3 ± 0.9) × 10<sup>−18 </sup>cm<sup>2</sup>. Rotational and vibrational temperatures of 870 K and 1340 K, respectively, are observed. State-resolved velocity distributions are observed, where one part can be described by a Maxwellian flux distribution with <E<sub>kin</sub>>/2k ranging from 1000 to 1800 K. In addition a faster component is present which gains in importance for increasing J″. A distinct rotation–translational coupling is found.
