Resonance-enhanced Multiphoton Ionization with circularly polarized light: chiral carbonyls
Analytical and Bioanalytical Chemistry, 2013Co-Authors: Ulrich Boesl, Alexander Bornschlegl, Christoph Logé, Katharina TitzeAbstract:An introduction to the principle and possibilities of the new method of circular dichroism laser mass spectrometry is given and its state of development is reviewed. This method allows enantiosensitive, mass-selective probing of chiral molecules. It is based on the combination of resonance-enhanced Multiphoton Ionization with circularly polarized light and specially modified time-of-flight mass spectrometry. As an example, application to carbonyls is presented. Figure The combination of resonance enhanced Multiphoton Ionization and circular dichroism performed in a time-of-flight mass spectrometer allows mass selective enantio-sensitive spectroscopy with new features for chiral analysis

Coherent microwave rayleigh scattering from resonance-enhanced Multiphoton Ionization in argon.
Physical review letters, 2007Co-Authors: Zhili Zhang, Mikhail N. Shneider, Richard B. MilesAbstract:Multiphoton Ionization and electron recombination processes are studied in argon using coherent microwave Rayleigh scattering from a localized, resonance-enhanced Multiphoton Ionization produced plasma. A time dependent one-dimensional plasma dynamic model is developed to predict the time evolution of the microwave scattering from the plasma. Experimental results of the argon Ionization spectrum and electron recombination rates are in good agreement with the model predictions.

Interference effects in the Multiphoton Ionization of sodium.
Physical review letters, 1995Co-Authors: Robert JonesAbstract:Sodium atoms are ionized by 777 nm, 150 fs laser pulses. Modulations are observed in the Multiphoton Ionization yield as a function of laser intensity. The oscillations are attributed to Ramsey interference caused by coherent population transfer between bound states at two different times during a single laser pulse.

Multiphoton Ionization and chemical dynamics
International Reviews in Physical Chemistry, 1995Co-Authors: Joseph J. BelbrunoAbstract:Abstract Multiphoton Ionization spectroscopy is a tool for the elucidation of the structure of high-energy states of atoms and molecules. Particularly when used in combination with time-of-flight mass spectrometry and photoelectron spectroscopy, the range of applications include pure spectroscopic studies, the quantum state specific detection of reactants and products and the preparation of quantumstate-selected reactants for chemical reactivity studies. As such, the techniques have become ubiquitous in the field of chemical reaction dynamics. This paper is concerned mainly with the describing the range of these applications and techniques and a selection of typical results.
