In concentrated solutions of NaClO4 and Na2SO4, the quantum yield for free electron generated by detachment from photoexcited anions (such as I-, OH-, ClO^4-, and [SO3]^2-) linearly decreases by 6-12% per 1 M ionic strength. In 9 M sodium perchlorate

Time-resolved transient absorption spectroscopy has been used to study electron dynamics in aqueous anatase nanoparticles (pH = 4, 4.6 nm diameter) in the presence of hole scavengers: chemisorbed polyols and carbohydrates. These polyhydroxy compounds

It is shown that 532 and 1064 nm laser photoexcitation of trapped electrons generated by 355 nm photolysis of aqueous titania (TiO2) nanoparticles causes rapid photobleaching of their absorbance band in the visible and near-IR. This photobleaching oc

Time resolved transient absorption spectroscopy has been used to determine quantum yields for electron photodetachment in 193 nm and (where possible) 248 nm laser excitation of miscellaneous aqueous anions, including hexacyanoferrate(II), sulfate, su

Transient absorption spectroscopy was used to study the mechanism for radiolysis of dense, liquidlike supercritical (sc) CO2 (T = 41 °C, ρ = 0.84 g/cm3). The 350−1500 nm spectra are decomposed into the contributions from the solvent radical catio

Time-resolved one- and two-pulse laser dc photoconductivity has been used to observe two kinds of reducing species, anion-1 and anion-2, in liquid acetonitrile. At 25 C, the standard enthalpy of conversion from anion-1 to anion-2 is -44.3 {+-} 3.6 kJ

Using time-resolved dc photoconductivity, the migration patterns and reactions of solvent hole in liquid methylcyclohexane between 230 and 350 K have been studied. It is shown that solvent holes in liquid methylcyclohexane are reversibly scavenged by

Time-resolved dc photoconductivity has been used to observe quasifree electrons and solvent radical anions in supercritical CO2 (ρc ≈ 0.468 g/cm3; Tc ≈ 31 °C). The electrons have lifetime τe 10 cm2/(V s). For ρ/ρc > 0.64, the product μeτe
