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(H2)=(4.9±0.4)×10-14, k(CH4)=(1.1±0.1)×10-12, k(C2H6)= (2.9±0.1)×10-11, k(C2H2)=(2.3±0.1) ×10-10, k(C2H4)=(2.7±0.1)×10-10, k(C3H6)=(2.3±0.3)×10-10, and k(O2)=(2.5±0.2)×10-11 cm3 molecule-1 s-1. A comparison with available literature data is made and mechanism are discussed.
