Electron affinities from gas chromatography electron capture detector and negative ion mass spectrometry responses and complementary methods

5-Nitro-2,4-Dichloropyrimidine as an Universal Model for Low-Energy Electron Processes Relevant for Radiosensitization

“…The gas phase adiabatic electron affinity based on the experimental data is 2.92 eV and calculated gas and liquid phase electron affinities are 2.11 eV and 3.58 eV, respectively. Similar to lifetime, also the electron affinity value is unusually high [49], it is more than twice as high as similar pure nitro-compounds [47]). The large electron affinity may result in the enhancement of the linear energy transfer (LET) to the tissue as described in the work of Postulka [31].…”

Detailed Characterization of Chlorides and Oxides in Plastic Waste Pyrolysis Oil from Paper Mills by GC-ECD and GC-MS with Solid Phase Extraction

“…However, it was unclear if these peaks were chlorides. Electronegative substances like those containing oxygen, nitrogen, and polycyclic aromatic hydrocarbons may also cause ECD signals, in addition to halogens . The PWPO studied in this work contained1400 mg/kg nitrogen and 36000 mg/kg oxygen.…”

Stabilization of phenanthrene anions in helium nanodroplets

“…Several experimental studies using the electron-capture detector technique which is based on the temperature dependent kinetics of electron attachment have reported adiabatic electron affinities (AEAs) of Ph close to 0.3 eV. 10–12,25–27 However, the validity of these data has been questioned, 5,14,15,28 partly because the mass of the formed anions has not been measured, and partly because theoretical values for the AEA of Ph are well below 0.3 eV, or even negative. 13,17,29,30 A benchmark study that includes structural relaxation and zero-point vibrational energy corrections places the AEA of Ph at −0.08 eV.…”
