State-Resolved Reaction Dynamics

Abstract

Resonance-Enhanced Multiphoton Ionization-Photoelectron Spectroscopy. A single time-of-flight (TOF) photo-electron spectrometer is to be used in conjunction with the MPI of jet-cooled molecules. This apparatus will measure energy and single-resolved photoelectron spectra. Such information has been of direct used in measuring the internal state distribution of REMPI-formed ions used in ion-molecule reaction studies. REMPI Spectroscopy of HBr and DBr. The laser induced fluorescence (LIF) technique has been developed to probe ion species. The ions produced directly from REMPI can have their rotational propensity roles in photoionization processes. The ions produced from a reaction between the state selected ions generated by REMPI and other molecules can be observed for studying state to state ion molecule reaction dynamics. State Selected Ion Molecule Reactions. The reactions of ammonia cations with neutral molecule, were conducted using a tandem quadropole mass spectrometer. A new tapole ion trap was proposed to increase vastly our control over and understanding of biomolecular ion-molecular reactions. To make the quadropole/ octapole/quadropole ion trap operational it was necessary to solve the technically challenging problem of interfacing three dissimilar radio frequency (rf) devices.
