Abstract— During the reaction HO2+ HO2 (or O2‐) = H2O2+ O2 in aqueous solution, no luminescence in the region 620–720 nm, expected if the product O2 were formed in a singlet state, could be detected. If any singlet O2 is formed, its yield must be less than 10%. Faint luminescence, sometimes found at shorter wavelengths, was shown to arise from reaction of HO2 with impurities in the reagents present.

Abstract The energy level V0 of electrons injected into liquid argon was determined over the range of temperatures and densities in which the electron mobility passes through a maximum. A minimum in V0 was found, not at the density of the mobility maximum as expected, but at a somewhat higher density.

Existing data on the kinetics of ascorbate radical decay, together with some new data on the effects of temperature, ionic strength, and presence of phosphate buffers, suggest a mechanism in which the ascorbate radical ion is in equilibrium with a dimer. This dimer reacts with hydrogen ion, or with other proton donors present including water and buffers (at rates depending upon their acid strengths), to form the disproportionation products ascorbate ion and dehydroascorbate acid.

When a liquid, placed in an electric field between coaxial cylindrical electrodes, is ionized uniformly by a short pulse of x rays, the current resulting from the subsequent motion of the inward-moving ions decays with time differently from that due to the outward-moving ions. This effect provides a convenient method, here described in detail, for assigning mobilities to the positive and negative ions present. Mobilities were determined as a function of temperature for the ions formed in dilute solutions of the electron-trapping molecules SF6, CH3I, CH3Br, CH3Cl, or O2 in cyclohexane or 2,2,4-trimethylpentane. In all these cases the negative ions were more mobile than the positive. Only one major negative ion mobility and one major positive ion mobility was to be seen in the solutions, with the exception of O2 in 2,2,4-trimethylpentane, which gave two negative ions of different mobilities.

The forward and reverse rates of the reaction CO2 + e− CO2− were determined in tetramethylsilane, neopentane and 2,2,4-trimethylpentane as a function of temperature. The forward reaction is exothermic in solution but the equilibrium constant shifts over four orders of magnitude with changes in solvent. The change in entropy for the forward reaction is approximately the same (−44 cal/mol degree) in the three solvents.

The yield of free ion pairs formed by 2-MeV x rays was determined in 38 pure liquids and in four mixed systems at room temperature, and in five liquids as a function of temperature. Marked effects of molecular constitution are found to be superimposed over the effects of dielectric constant and density of the liquids.

The drift mobilities of electrons in eight saturated hydrocarbons and in tetramethylsilane were determined from the rise time in the conductivity found with a fast-response circuit when a parallel-plate cell was subjected to a pulse of 2-MeV x rays. Careful purification was required to avoid capture of the electrons by impurity centers. The measured mobilities ranged from 0.09 cm2 V−1·sec−1 in n-hexane to 90 in tetramethylsilane. Drift velocities were linear with the applied field up to velocities above 106 cm/sec. Temperature coefficients of the mobility were found to be positive in n-hexane and neohexane. Speculations are offered about the nature of the processes which determine the mobilities.

A method has been developed for determining the yield of free ions formed by irradiation of a liquid with high-energy x-rays. Contrary to expectation, branched-chain paraffins produce many more free ions than straight-chain paraffins do, and the ether 1,4-dioxane produces only a third as many free ions as its hydrocarbon analog, cyclohexane.
