Dissociative electron attachment to triflates

The Journal of Chemical Physics, 2011
Gas phase studies of dissociative electron attachment to simple alkyl (CF3SO3CH3) and aryl (C6H5SO3CF3 and CF3SO3C6H4CH3) triflates, model molecules of nonionic photoacid generators for modern lithographic applications, were performed. The fragmentation pathways under electron impact below 10 eV were identified by means of crossed electron-molecular ...

Dissociative Electron Attachment to DNA

Physical Review Letters, 2003
Electron-stimulated desorption of anions from thin films of linear and supercoiled DNA is investigated in the range 3-20 eV. Resonant structures are observed with maxima at 9.4+/-0.3, 9.2+/-0.3, and 9.2+/-0.3 eV, respectively, in the yield dependence of H-, O-, and OH- on the incident electron energy.

Dissociative electron attachment in NO

The Journal of Chemical Physics, 1991
Previously reported experimental data on dissociative electron attachment (DEA) in NO are reinterpreted. The negative-ion yield resulting from DEA in NO has peak intensities at electron energies around 8 and 9 eV. It is demonstrated that the 8 and 9 eV peaks are due to O− ions and long-lived N− ions, respectively.

Dissociative electron attachment studies on acetone

The Journal of Chemical Physics, 2014
Dissociative electron attachment (DEA) to acetone is studied in terms of the absolute cross section for various fragment channels in the electron energy range of 0–20 eV. H− is found to be the most dominant fragment followed by O− and OH− with only one resonance peak between 8 and 9 eV.

Dissociative Electron Attachment to Molecular Acetonitrile

The Journal of Physical Chemistry A, 2019
Low-energy dissociative electron attachment to molecular acetonitrile (CH3CN) is investigated by recording the efficiency curves of CH2CN-, CHCN-, and CN- products, but the present curves are distinctly different from those in the previous reports.

Resonances and Dissociative Electron Attachment in HNCO

Physical Review Letters, 2018
In a combined experimental and theoretical study, we probe the dissociative electron attachment in isocyanic acid HNCO. The experimental absolute cross section for the NCO^{-} fragment shows a sharp onset and fine structures near the threshold. The autoionizing state responsible for the dissociative attachment is found in both the R-matrix calculation ...

Dissociative electron attachment in selected haloalkanes

Rapid Communications in Mass Spectrometry, 2006
Abstract Three mono‐substituted and six poly‐substituted haloalkanes derivatives were investigated by means of negative ion mass spectrometry (NIMS). Available electron transmission spectroscopy (ETS) data were used for the treatment of NIMS results.

Dissociative electron attachment to OCS

Journal of Molecular Structure: THEOCHEM, 1995
Abstract The formation of S− and C− ions from electron impact on OCS has been investigated by using a crossed electron beam-molecular beam collision geometry. Measured appearance energies and peak energies for the formation of S− and C− ions are reported.

Dissociative electron attachment to hydrogen

Journal of Physics B: Atomic, Molecular and Optical Physics, 2001
Using two different crossed-beams high-resolution electron attachment instruments (employing either a trochoidal electron monochromator or a hemispherical electron monochromator) we have determined the cross section curve for H- production from H2 via the 4 eV resonance at two different temperatures.

Dissociative electron attachment to acetylene

Physical Review A, 2008
The mechanism and cross section for dissociative electron attachment of acetylene after collision with electrons in the 0--7 eV range is reported. The positions of the resonances and the autoionization widths are determined by electron scattering calculations using the complex Kohn variational method.
