Abstract
The mechanism of formation of negative ions of trinitrotoluene, dinitrotoluene, and para-nitrotoluene in the gas phase under the action of laser irradiation was studied using ion mobility spectrometry. The gas mixture was ionized by the fourth harmonic radiation of a YAG:Nd3+ laser. The irradiance was varied within 2–5 MW/cm2. It was demonstrated that, although the test compounds are characterized by a high cross section of absorption of laser radiation the formation of their anions occurs largely through the multiphoton ionization of organic admixtures present in the gas mixture with the subsequent attachment of electrons formed. In a nitrogen medium, the attachment of electrons occurs directly, whereas in air, the O −2 immediate plays an important role. Laser radiation causes the dissociation of the molecules under study, especially marked for para-nitrotoluene.
