COMMENTS: | Shock heating of stoichiometric hydrogen/oxygen mixtures (oxygen absorption after short reaction times)
A microwave N2 discharge lamp was used to generate light of 174 nm
Smooth fit for the temperature dependence of the effective extinction coefficient α(T) in cm2/mol (base e) for T = 840-2250 K:
log10 α(T) = 5.22 + 7.62 × 10-4 T - 1.57 × 10-7 T2
converted to absorption cross sections (conversion factor α(T) → σ(T) is 1.66×10-24) |
