WebNov 19, 2024 · Multiphoton ionization occurs when ionization follows the absorption of more than one photon by a molecule in the presence of an intense visible or UV light source. As the laser source is tuned to an allowed n-photon transition, the process is greatly enhanced. This is called resonance enhanced multiphoton ionization, REMPI. WebSep 11, 2024 · Resonance enhanced multiphoton ionization (REMPI) is a powerful method for the sensitive determination of polycyclic aromatic hydrocarbons (PAHs) in gaseous mixtures via mass spectrometry (MS). In REMPI, ions are produced by the absorption of at least two photons including defined electronic intermediate states. As a result—unlike … WebThe resonance two-photon ionization (R2PI) spectra of the jet-cooled aniline dimers (An-d0)2, (An-d5)2, and (An-d7)2 have been recorded; the first 225 cm-1 region above the (An-d0)2 origin was also reproduced by fluorescence excitation spectroscopy. Relatively sharp structure near the origin of the local excited state is attributed to intermolecular modes, … sailing association of intermountain lakes
