SUPPLEMENTARY NOTES ABSTRACTExperiments were carried out using a flowing-afterglow Langmuir-probe apparatus to measure rate constants for electron attachment to SF 6 and thermal detachment from SF 6 '. In a recent series of papers, these results were combined with new and existing data on nondissociative and dissociative attachment to SF 6 and compared to statistical modeling of the various processes involved in the stabilization of the ionic products of attachment. This paper gives a summary of those findings. The major conclusions are: (a) only the ground electronic state of SF 6 needs to be invoked to explain available data; (b) the electron affinity of SF 6 is higher than previously thought, namely, EA(SF 6 = 1.20 (± 0.05) eV; (c) the endothermicity of the dissociative electron attachment reaction that yields SF 5 " is 0.41 eV (± 0.05) eV at 0 K: (d) combining these two numbers gives the bond energy D 0°( F-SF 5 ") = 1.61 (± 0.05) eV.

IntroductionIn three earlier papers we delineated various aspects of electron attachment to SF 6 and the reverse detachment from SF 6 " under thermal and low-energy conditions (electron energies less than about 0.4 eV).'" 3 There exists also a wealth of information on the higher energy processes, but those are outside the scope of the present study. For a more detailed discussion of the higher-energy processes,...

Electron Attachment to C7F14, Thermal Detachment from C7F14–, the Electron Affinity of C7F14, and Neutralization of C7F14– by Ar+

“…Electron attachment to C 7 F 14 is also of interest because of parallels to SF 6 attachment, which has been studied extensively, including our own recent efforts. − SF 6 and C 7 F 14 are somewhat unique in being stable neutrals that rapidly associatively attach electrons to yield stable parent anions competing with minor dissociative channels. Additionally, ion equilibrium experiments by Grimsrud et al showed that the electron affinity (EA) of C 7 F 14 is the same as that of SF 6 within their experimental uncertainty .…”

Electrostatic Neutralization Characteristics of an AC‐Corona‐Discharge‐Type Ionizer in Mixed N2‐O2, N2‐SF6 Atmosphere

“…This difference is considered due to the area of cross section for electron to attach thereon. Figure summarizes the correlation of the electron attachment cross section of O 2 and SF 6 with electron energy . The anions derived from oxygen are generated by dissociative electron attachment reaction as follows: …”

Reactions of Negative Ions with ClN3 at 300 K

“…Calculations of SF 6 -and SF 5 -energetics have been shown to be difficult and inaccurate. 29 In reactions with both anions, FN 3 -is formed, likely through a syn attack on the terminal nitrogen and elimination of SF x-1 Cl. The production of SF 4 N 3 -and SF 5 -, which would both result in the production of neutral ClF, likely occurs through the same mechanism.…”
