【 摘 要 】
The hydrogen atom migration preceding fragmentation of the pyridine molecules by the H+, H2+, He+and He++collisions has been investigated in the 5-2000 eV energy range. The pyridine molecule structure is lacking of the NH group, thus formation of the NH radicals is an evidence of the H atom relocation prior to the cation-induced fragmentation. The NH(A3Π) fragmentation yields measured by detecting its A3Π→X3Σ-fluorescence show that it depends on the selected projectile and the projectile velocity.
