The pulsed laser photolysis (PLP), time‐resolved laser‐induced fluorescence (LIF) technique has been used to study the association reaction CH + N 2 in a CRESU (Cinétique de Réaction en Ecoulement Supersonique Uniforme) apparatus at 53 K and in the pressure range 0.46–6 mbar. The third order rate constant was found to be k o = (5.7±0.30) × 10 −30 cm 6 s −1 . Consequences for the production of HCN in the atmosphere of Triton are discussed in light of this result.
