Pyridyl radicals are the prototypical heterocyclic radicals containing nitrogen as a heteroatom. Since pyridine is one of the main components of heterocycles in fossil fuels, the formation of pyridyl radicals has been suggested as a possible intermediate in combustion processes. The decomposition of pyridine has been the subject of numerous detailed experimental and theoretical studies, which have shown that the thermal decomposition of pyridine produces, among others, cyanide, acetylene, and hydrogen, starting with the cleavage of the C-H bond that initiates a decomposition cascade with diverse pyrolysis products.
We present measurements on pyridine conducted at the DESIRS beamline at Synchrotron Soleil in France employing the fluorine discharge reactor. One and two Hydrogen loss products are observed and are characterized by evaluating their slow photoelectron spectra and corresponding franck condon simulations.
