Abstract:

Resonance enhanced multiphoton ionization (REMPI) spectroscopy, preferably linked with kinetic energy analysis of the resulting photoelectrons (REMPI-photoelectron spectroscopy (PES)), continues to make enormous contributions to our understanding of the spectroscopy and, in many cases, the decay dynamics of small molecules in excited (normally Rydberg) electronic states. Here we present results of recent REMPI and REMPI-PES studies involving the ammonia molecule which provide further illustration of some of the many opportunities offered by these techniques.
