Abstract

The two-laser photoinitiation/probe technique has been used to obtain room-temperature second-order rate constants for the reaction of CN radicals with compounds key to atmospheric and combustion chemistry. CN was generated by 266 nm photolysis of ICN. Laser-induced flourescence probing via both CN(A ← X) and CN(B ← X) has been utilized. Values reported are: k(H ₂ )=(4.9±0.4)×10 ^-14 , k(CH ₄ )=(1.1±0.1)×10 ^-12 , k(C ₂ H ₆ )= (2.9±0.1)×10 ^-11 , k(C ₂ H ₂ )=(2.3±0.1) ×10 ^-10 , k(C ₂ H ₄ )=(2.7±0.1)×10 ^-10 , k(C ₃ H ₆ )=(2.3±0.3)×10 ^-10 , and k(O ₂ )=(2.5±0.2)×10 ^-11 cm ³ molecule ^-1 s ^-1 . A comparison with available literature data is made and mechanism are discussed.
