EXCITED-STATE MOLECULAR PHOTOIONIZATION DYNAMICS

This review presents a survey of work using resonance-enhanced multiph oton ionization and double-resonance techniques to study excited-state photoionization dynamics in molecules. These techniques routinely pro vide detail and precision that are difficult to achieve in single-phot on ionization from the ground state. The review not only emphasizes ne w aspects of photoionization revealed in the excited-state experiments but also shows how the excited-state techniques can provide textbook illustrations of some fundamental mechanisms in molecular photoionizat ion dynamics. Most of the examples are confined to diatomic molecules.
