Identification of Isomers of Nitrotoluene via Free Electron Attachment

Free electron attachment to the three different isomers of mononitrotoluene molecules in the gas phase is studied using a crossed electron−molecule beams technique. In contrast to previous studies for a large number of negative ions, the presently measured relative cross section curves are recorded...

Description
Summary:Free electron attachment to the three different isomers of mononitrotoluene molecules in the gas phase is studied using a crossed electron−molecule beams technique. In contrast to previous studies for a large number of negative ions, the presently measured relative cross section curves are recorded with an electron energy resolution of better than 100 meV. For several product anions including the nitro anion NO2 -, remarkable differences for the three isomers are observed. In almost all fragment anion efficiency curves, the 2-nitrotoluene exhibits pronounced differences from the two other isomers. In contrast, 3- and 4-nitrotoluene disagree only slightly in a few fragment anions from each other.
