Interactive comment on “Hydrogen isotope fractionation in the photolysis of formaldehyde” by T. S. Rhee et al

چکیده
Q: The terms ’incomplete photolysis’ (R1) and ’complete photolysis’ (R2) are defined in the introduction, referring to the H + HCO and CO + H2 product channels in formaldehyde photolysis respectively. This terminology is confusing, because the experimental procedure relies on the complete photolysis of an HCHO sample to products, presumably involving some amount of both the ’complete’ and ’incomplete’ pathways. These two reactions are usually called the radical channel and the molecular channel. For example, page 12749, caption to Figure 4, it is written ’...that the complete photolysis of CH2O yields H2 with a dD value that is the same as that of the initial CH2O.’ It is unclear whether this means ’100% photolysis of CH2O via R1 and R2 but leading to

متن کاملPressure dependence of the deuterium isotope effect in the photolysis of formaldehyde by ultraviolet light
The pressure dependence of the relative photolysis rate of HCHO vs. HCDO has been investigated for the first time, using a photochemical reactor at the University of Copenhagen. The dissociation of HCHO vs. HCDO using a UVA lamp was measured at total bath gas pressures of 50, 200, 400, 600 and 1030 mbar. The products of formaldehyde photodissociation are either H2 + CO (molecular channel) or HC...
متن کاملAtmospheric deuterium fractionation: HCHO and HCDO yields in the CH2DO + O2 reaction
The formation of formaldehyde via hydrogen atom transfer from the methoxy radical to molecular oxygen is a key step in the atmospheric photochemical oxidation of methane, and in the propagation of deuterium from methane to molecular hydrogen. We report the results of the first investigation of the branching ratio for HCHO and HCDO formation in the CH2DO + O2 reaction. Labeled methoxy radicals (...
متن کاملIsotope effect in the formation of H2 from H2CO studied at the atmospheric simulation chamber SAPHIR
Formaldehyde of known, near-natural isotopic composition was photolyzed in the SAPHIR atmosphere simulation chamber under ambient conditions. The isotopic composition of the product H2 was used to determine the isotope effects in formaldehyde photolysis. The experiments are sensitive to the molecular photolysis channel, and the radical channel has only an indirect effect and cannot be effective...
متن کاملHydrogen Isotope Fractionation between HC12" Ion and HCl
Hydrogen isotope fractionation between hydrogen dichloride ion in the condensed phase and gaseous hydrogen chloride has been studied both theoretically and experimentally. Quite good agreement between the experimental tritium fractionation factor and that theoretically calculated for two sets of vibrational data was found. Theoretical calculations of the fractionation factors of both deuterium ...
