Dehydrogenation of adenine induced by slow (<3 eV) electrons

Low energy (<3 eV) electrons impact to gas phase Adenine generates the dehydrogenated Adenine negative fragments, (A–H)−, and an H-atom neutral radical counterpart. Within the energy range of 0.7–2.8 eV, production of (A–H)− arises from Dissociative Electron Attachment (DEA). In addition, a sharp peak is observed at near 0 eV. This peak is identified to arise from dissociative electron transfer reaction of SF6− (from the calibration gas) with Adenine.
