The reaction of OH radicals with CH4 has been investigated over the temperature range 290-440°K in a flow system with UV resonance fluorescence detection of OH. Its rate constant can be represented in Arrhenius form as k1 = 3.83 × 10−12 exp(−3660(cal/mole)/RT) cm³ sec−1....

The rate constants for the reaction of OH with SO(M=He, Ar, N, O, CO, and SO) have been determined in a discharge flow system with an OH resonance fluorescence detector. The results are as follows: k(M=He) = (7.91 +/- 0.24) x 10(T/298)/sup -(2.85 +- 0.21)/ (261-414 ...
The reaction ofC+(2P)with CH4has been investigated in the 2–200‐eV energy region using a tandem mass spectrometer. All possible ions containing one or two carbon atoms were observed except C2H4+. The behavior of the cross sections as a function of the kinetic energy of the incident ion ...

Methane, the simplest alkane, is one of the most important and abundant carbon molecules on Earth. It is a major supply of energy, a chemical feedstock, and a potent greenhouse gas. Aside from thermogenic, pyrogenic, and abiotic sources, methane is prima
reaction rate with OH was competitive with the reaction rate of OH with CH4. The profiles in Fig.3were modelled (Supplementary Figs.6,7) with the O3photolysis rate andφCH3OHas the only adjustable parameters. Reaction conditions and depletions were chosen such that the reaction of CH3OO with...
Reaction rates of the reactions of OH(X 2 Π ) with NH(a 1 Δ ) and HN 3 (X) The rate constants of the radical–radical reaction OH(X 2Π)+NH(a 1Δ)→products and the radical–molecule reaction OH(X 2Π)+HN3→products were determined in a quasistatic laser photolysis cell at ...
The total vibrational distribution of OH product in the reaction O ( 1D) + CH 4 was found to be much hotter than the statistical distribution P(ν=0): P(ν=1): P(ν=2): P(ν=3): P(ν=4) = 0.18: 0.29: 0.37: 0.15: 0.01. The rate constants for vibrational relaxation of OH(...
