Journal ArticleDOI
Visible and UV multiphoton ionization and fragmentation of polyatomic molecules
TL;DR: In this paper, the authors used time delayed tandem laser pulses of different wavelengths to study the mechanism of this multiphoton ionization and fragmentation process in benzene and showed that excitation does not proceed up an autoionization ladder of the neutral molecule, rather the multi-hoton process is due to climbing of two independent ladders, one up to the ionization potential in the neutral molecules, the second in the new species of molecular parent ions produced.
Journal ArticleDOI
Multiphoton mass spectrometry of metastables: direct observation of decay in a high-resolution time-of-flight instrument

TL;DR: It was demonstrated that laser mass spectrometry (REMPI-TOFMS) enables a real-time on-line trace analysis of combustion flue gases or industrial process gases.
Journal ArticleDOI
Multi-photon ionization in the mass spectrometry of polyatomic molecules: Cross sections
TL;DR: In this article, multi-photon ionization (MPI) with tunable visible/UV laser light is shown to be a sensitive tool for analysis of traces in gas mixtures when combined with a mass spectrometer.
Journal ArticleDOI
Reflectron time-of-flight mass spectrometry and laser excitation for the analysis of neutrals, ionized molecules and secondary fragments
TL;DR: Reflection time-of-flight mass spectrometry in combination with laser ionization is described in this article, with special emphasis on the spatial focus of an ion source and on reflection techniques for correction of these time-ofthe-flight uncertainties.
