VUV photoionization cross sections of HO2, H2O2, and H2CO.
The absolute vacuum ultraviolet (VUV) photoionization spectra of the hydroperoxyl radical (HO2), hydrogen peroxide (H2O2), and formaldehyde (H2CO) have been measured from their first ionization thresholds to 12.008 eV. HO2, H2O2, and H2CO were generated from the oxidation of methanol initiated by pulsed-laser-photolysis of Cl2 in a low-pressure slow flow reactor. Reactants, intermediates, and p...
متن کاملPeroxone chemistry: formation of H2O3 and ring-(HO2)(HO3) from O3/H2O2.
The recent observation [Wentworth, P., Jones, L. H., Wentworth, A. D., Zhu, X. Y., Larsen, N. A., Wilson, I. A., Xu, X., Goddard, W. A., Janda, K. D., Eschenmoser, A. & Lerner, R. A. (2001) Science 293, 1806-1811] that antibodies form H(2)O(2) from (1)O(2) plus H(2)O was explained in terms of the formation of the H(2)O(3) species that in the antibody reacts with a second H(2)O(3) to form H(2)O(...
متن کاملInitiation in H2/o2: Rate Constants for H2 O2 → H Ho2 at High Temperature
The reaction between H2 and O2 has been studied in a reflected shock tube apparatus between temperatures of 1662–2097 K and pressures of 400–570 torr with Kr as the diluent gas. O atom atomic resonance absorption spectrometry (ARAS) was used to observe absolute [O]t under conditions of low [H2]0 so that most secondary reactions were negligible. Hence, the observed [O]t was the direct result of ...

متن کاملProduction of HO2 and O2 by multiple ionization in water radiolysis by swift carbon ions
We present a simulation of liquid water radiolysis by swift carbon ions that explicitly takes into account multiple ionization of water molecules. For high linear energy transfer (LET), this process is not negligible with respect to single ionization. The rearrangement of highly ionized water molecules is consistent with production of atomic oxygen. Multiple ionizations is shown to be responsib...
