“…observed in two previous studies employing He photoelectron spectroscopy[34,35]. Our IEa estimate is consistent with the value of 8.02 eV put forward by Behan et al[35]. Baker and co-workers[34] estimated adiabatic and vertical IEs of 7.65 and 8.4 eV; our results suggest less of a difference between the two values.…”

Effect of Solvents on Persistent Free Radical Content in the Absence of Reactions

The impact of a solvent environment on persistent free radical concentrations at ambient conditions was studied by electron spin resonance spectrometry. The analyte selected was Canadian oil-sand-derived bitumen due to its high persistent free radical content. The ability of 54 different solvents to produce a homogeneous 5 wt % solution of bitumen was evaluated. The influence of solvents on the free radical content in bitumen was determined exclusively for solvents that were capable of quantitatively dissolving the bitumen. These were compounds in the classes of alkynes, mono-and bicyclic benzene-derivatives, and heteroatom-containing compounds containing nitrogen, oxygen, sulfur, and chlorine. It was found that a shift in the g-factor of bitumen occurred when the solvent was changed. The shift was attributed to the radical−solvent interaction that is affected by the polarity of the solvent and reflected in the solvent dipole moment property. The change in the free radical concentration was independent of changes in g-factor and was not correlated with any of the following solvent properties: molecular weight, dipole moment, dielectric constant, refractive index, density, and viscosity. There was a relationship between the free radical concentration in bitumen and the ionization potential of sulfur-containing and diaromatic hydrocarbon solvents. It was concluded that the bulk liquid properties that affected the electronic environment of the free radical species, resulting in a shift in g-factor, were not related to the bulk liquid properties that affected the dissociation equilibrium and resulted in a change in the free radical concentration.

“…Figure 5). Potential species at lower ionization energies are tetrahydrofuran with an IE close to 9.40 eV (Behan et al (1976); Doucet et al (1972);Hernandez (1963)) and the likely species 2-butanone (IE = 9.52 eV (Traeger (1984))), iso-butanal (IE = 9.71 eV (Hernandez et al (1977))), and n-butanal (IE = 9.83 eV (Traeger & McAdoo (1986))). At higher photon energies, dimethyloxirane isomers may be detected, although they are unlikely to be contributing to the ms-TPES, since their IE is close to the maximum energy of the energy scan (10.3 eV) near 10.0 eV (Eskola et al (2017)).…”

“…Panel (a) of Figure 5 shows the PI spectrum and marked literature reference ionization energies (Hernandez (1963); Doucet et al (1972); Behan et al (1976); Traeger (1984); Hernandez et al (1977); Traeger & McAdoo (1986)). The late onset of the PI spectrum shows no evidence for the presence of tetrahydrofuran.…”
