Infrared detection of HO2 and HO3 radicals in water ice.
Infrared spectroscopy has been used to detect HO(2) and HO(3) radicals in H(2)O + O(2) ice mixtures irradiated with 0.8 MeV protons. In these experiments, HO(2) was formed by the addition of an H atom to O(2) and HO(3) was formed by a similar addition of H to O(3). The band positions observed for HO(2) and HO(3) in H(2)O-ice are 1142 and 1259 cm(-1), respectively, and these assignments were con...
متن کاملFugacity Coefficients of Saturated Water from Molecular Simulation
We apply isothermal-isobaric Monte Carlo molecular simulation to measure the vapor-phase fugacity coefficients and equation of state of three fixed-charge models of water: SPC/E, MSPC/E, and TIP3P. State conditions correspond to the experimental vapor-liquid saturation pressures for temperatures between 292.65 and 386.85 K. The results are compared to the experimental data for water vapor. We a...
متن کاملElectrochemistry in supercritical fluids
A wide range of supercritical fluids (SCFs) have been studied as solvents for electrochemistry with carbon dioxide and hydrofluorocarbons (HFCs) being the most extensively studied. Recent advances have shown that it is possible to get well-resolved voltammetry in SCFs by suitable choice of the conditions and the electrolyte. In this review, we discuss the voltammetry obtained in these systems, ...
متن کاملFate of oxygen free radicals in extracellular fluids.
1. Oxygen radicals in biological systems and the importance of iron Oxygen radicals can be either organic or inorganic. The organic radicals such as the peroxy (ROO') and alkoxy (RO') are those derived from complex molecules like the polyunsaturated fatty acids. The inorganic oxygen radicals are the superoxide radical (O,-*) and the hydroxyl radical (OH'). Formation of the highly reactive hydro...
متن کاملDispersion Coefficients of Supercritical Fluid in Fixed Beds
The axial dispersion coefficient of hexachlorobenzene in supercritical carbon dioxide is investigated in a fixed-bed packed with glass beads. The on-line chromatographic pulse-response experiment is used in order to study the dynamics of a packed column under supercritical conditions. The radial dispersion is assumed negligible because of the packed column geometry. To estimate the axial disper...
