An electron-swarm mass-spectrometric study of electron attachment to thiophenol and its anion–molecule reactions

Electron attachment to ground-state thiophenol, C 6H 5SH, has been studied using an ion-mobility mass spectrometer. Mean electron energies from about 1.23 eV up to about 1.46 eV were covered using an atmospheric-pressure argon buffer gas and various density-reduced electric field strengths, E/ N, fr...

Description
Summary:Electron attachment to ground-state thiophenol, C 6H 5SH, has been studied using an ion-mobility mass spectrometer. Mean electron energies from about 1.23 eV up to about 1.46 eV were covered using an atmospheric-pressure argon buffer gas and various density-reduced electric field strengths, E/ N, from 2.48 up to 3.55×10 −18 V cm 2 in a drift chamber. It was found that thiophenol attaches low-energy electrons only dissociatively and three fragment anions were observed: CH 2S −, C 2H 5S − and C 6H 5S −. These findings are discussed.
