Abstract

The rate constant for the reaction between CH3 and CH2 (X̃3B1 = 3CH2) radicals, CH3+3CH2 → products, (1) was determined at T=298 K and p= 1.33 mbar in an isothermal discharge flow reactor. Far Infrared Laser Magnetic Resonance (FIRLMR) was employed for monitoring 3CH2 and CH3 radical concentration-versus-time profiles. CH3 was determined in the form of NO via the conversion reaction CH3+NO2 → CH3O+NO. The CH3 and 3CH2 radicals were generated by the reactions F+CH4 → CH3+HF and F+CH33CH2+HF. The rate constant for the recombination reaction CH3+CH3+M → C2H5+M (2) was determined together with the rate constant for reaction (1). The measurements gave a rate constant value for reaction (1) of k1=(6.5±1.2)-1013 cm3/mol s.
