Abstract
The pulsed laser photolysis (PLP), time-resolved laser-induced fluores cence (LIF) technique has been used to study the association reaction CH + N-2 in a CRESU (Cinetique de Reaction en Ecoulement Supersonique Uniforme) apparatus at 53 K and in the pressure range 0.46 mbar. The t hird order rate constant was found to be k(0) = (5.7 +/- 0.30) x 10(-3 0) cm(6) s(-1). Consequences for the production of HCN in the atmosphe re of Triton are discussed in light of this result.
