N2 - NO molecules adsorbed on a Pd(110) surface undergo desorption with maxima at approximately 495 K at low coverage but two desorption peaks at approximately 370 K and 495 K at high coverage. Desorption of NO at 495 K mediates the emission of N2 and N2O. However, desorption of NO at 370 K produces neither N2 nor N2O. NO molecules desorbed at 495 K obey cos θ towards the 〈001〉 direction, whereas the N2 molecules emitted at 495 K have a very sharp spatial distribution 37° off-normal to the surface in the 〈001〉 direction. The emission of N2 has a full width at half maximum (FWHM) of 19° which can be represented by cos46(θ - 37). The spatial distributions of N2 and NO in the 〈11̄0〉 direction, however, obey cos4.2θ and cos1.6θ, respectively.
