摘要

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.
