The angular distribution of desorbing N₂ was studied in the decomposition of N₂O(a) on Rh(1 1 0) at 50-200 K with angle-resolved thermal desorption. N₂ desorption showed five peaks at around 70 K (β₅-N₂), 95 K (β₄-N₂), 115 K (β₃-N₂), 140 K (β₂-N₂), and 160 K (β₁-N₂). β₁-N₂ yielded a cosine distribution, whereas the others involved desorption components that collimated at either 69±3° or 27±3° off normal into the [0 0 1] direction. The 27° component was suppressed on clean (1×1) facets. The 69° component is proposed to be due to decomposition of N ₂O oriented in the [0 0 1] direction.
