Abstract

Rates of reaction of atomic oxygen (³P) with straight chain alkanes (C₁-C₅) and fluoromethanes (CH₃F) and CHF₃) have been measured at temperatures above 850 K by a laser flash photolysis-shock-tube technique coupled with atomic resonance absorption spectrometry. Measured rate constants agreed well with a recent TST calculation for O+CH₄ and O+C₂H₆. However, a small deviation from the TST calculation was found for O+C₃H₈ and larger alkanes. Preferable modified Arrhenius expressions for these reactions are presented. A good Evans-Polanyi correlation was found for the reactions investigated in the present study.
