Resonance Enhanced Multiphoton Ionization of Molecules and Molecular Fragments

Abstract

We have completed studies of ion rotational distributions produced by resonance enhanced multiphoton ionization of excited states of molecules and by single-photon ionization of ground states of jet-cooled molecules by coherent VUV radiation. The objective of this effort was to provide a robust analysis and prediction of key spectral features of interest in related experimental studies and technological applications of these laser-driven ionization techniques. Specific achievements include: identification of underlying mechanisms for anomalous behavior of ion rotational distributions in laser ionization of molecules and molecular fragments, development of schemes for exploiting such anomalous behavior to achieve state-selective production of ions, and providing needed insight into the underlying dynamics of state-resolved molecular photoionization.
