Abstract

Pulsed laser excitation in the near ultraviolet is found to be an effective method for the production of free radicals and atoms. Processes requiring numerous photons can be driven with high efficiency, producing large yields of atomic and small polyatomic fragments. The results are similar to those seen for the multiphoton fragmentation of molecular ions formed by multiphoton ionization processes. In this work, multiphoton ionization coupled with MS and PES detection is used to study the neutral products formed from both small and large polyatomic precursors.
