Journal ArticleDOI
Gas-Phase Infrared Spectrum of the Protonated Water Dimer
Knut R. Asmis,Nicholas L. Pivonka,Nicholas L. Pivonka,Gabriele Santambrogio,Mathias Brümmer,Cristina Kaposta,Daniel M. Neumark,Daniel M. Neumark,Ludger Wöste +8 more
TL;DR: The experiment directly probes the shared proton region of the potential energy surface and reveals three strong bands below 1600cm−1 and one at 1740 cm−1 (for H5O2 +), which highlight the importance of intermode coupling in sharedProton systems.
Journal ArticleDOI
Mass-selective vibrational spectroscopy of vanadium oxide cluster ions.
Knut R. Asmis,Joachim Sauer +1 more
TL;DR: Progress made in this research area is highlighted by reviewing recent infrared photodissociation (IR-PD) experiments on small and medium sized vanadium oxide ions by using a combination of modern experimental and quantum chemical approaches.
Journal ArticleDOI
Infrared Spectroscopy of the Microhydrated Nitrate Ions NO3−(H2O)1−6†
Daniel J. Goebbert,Etienne Garand,Torsten Wende,Risshu Bergmann,Gerard Meijer,Knut R. Asmis,Daniel M. Neumark +6 more
TL;DR: The onset of extensive water-water hydrogen bonding is observed starting with four water molecules and persists in the larger clusters, indicating an ion with a highly symmetric solvation shell.
Journal ArticleDOI
Spectroscopic snapshots of the proton-transfer mechanism in water
Conrad T. Wolke,Joseph A. Fournier,Joseph A. Fournier,Laura C. Dzugan,Matias Ruben Fagiani,Matias Ruben Fagiani,Tuguldur T. Odbadrakh,Harald Knorke,Kenneth D. Jordan,Anne B. McCoy,Anne B. McCoy,Knut R. Asmis,Mark A. Johnson +12 more
TL;DR: It is reported how the much simpler vibrational spectra of cold, composition-selected heavy water clusters, D+(D2O)n, can be exploited to capture clear markers that encode the collective reaction coordinate along the proton-transfer event.
Journal ArticleDOI
Cryogenic ion trap vibrational spectroscopy of hydrogen-bonded clusters relevant to atmospheric chemistry
TL;DR: In this article, recent advances in the gas phase vibrational spectroscopy of mass-selected ions are described, highlighting experiments on hydrogen-bonded (HBed) clusters relevant to atmospheric chemistry.
