Abstract
The multiphoton ionization of the simplest aromatic amine, aniline, was examined utilizing a kinetic energy-correlated time-of-flight mass spectrometer at a wavelength of 266 nm. The primary and secondary fragment channels have been identified, and their plausible internal energy dependence has been discussed. Furthermore, the sequential loss fragment channel has been analyzed using the energy-correlated mass spectrum, revealing the fragment channels along with their respective parent mass exclusively. The computed energetics are corroborated with the experimental findings to further support the dissociation hierarchy.
