Rate Constants for the Decay and Reactions of the Lowest Electronically Excited Singlet State of Molecular Oxygen in Solution. An Expanded and Revised Compilation24(1995); http://dx.doi.org/10.1063/1.555965View Description Hide Description
An expanded and revised compilation on the reactivity of singlet oxygen, the lowest electronically excited singlet state of molecular oxygen, 1O2 *(1Δg), in fluid solution is presented, which supersedes the publication of Wilkinson and Brummer, J. Phys. Chem. Ref. Data 10, 809 (1981). Rate constants for the chemical reaction and physical deactivation of singlet oxygen available through 1993 have been critically compiled. Solvent deactivation rates (k d) are tabulated for 145 solvents or solvent mixtures and second‐order rate constants for interaction of singlet oxygen with 1915 compounds are reported.

Recommended thermochemicalproperty values, Δ f H°, Δ f G° and S° for the aqueous ion of barium, Ba2+, are given at 298.15 K in SI units. The values are: Δ f H°=534.64±1.80 kJ⋅mol−1, Δ f G°=−557.60±1.81 kJ⋅mol−1 and S°=8.80±0.50 J⋅K−1 mol−1. They are consistent with the CODATA Key Values for Thermodynamics. The evaluation involves the analysis of the enthalpy changes, Gibbs energy changes, and the entropy measurements for all key substances in the key network. A consistent set of thermochemicalproperty values is given for BaO(cr), BaH2(cr), BaCl2(cr), BaCl2⋅2H2O(cr), Ba(NO3)2(cr), and BaCO3(cr,witherite), as well as reconstituted recommended process values with uncertainties for reactions involving these substances.
